    Site Updated 🍔🍺​​​​​​​

    Yes, this font size and color isn't the best for aging eyes. But I've found if I click Ctrl and + keys it enlarges everything and makes it much easier to read. The other thing I'm missing is numbers on each post in a thread. I sometimes use the number when replying in a thread to link back to a previous post in that thread. But maybe I'm the only one who misses the post numbers and I'll get along without them. Other than that, the new look is great. Over the last couple of days, I've been on Gmail, eBay, Photobucket, and YouTube. I can find waaay more to bitch about with all those sites than with Ratsun. Ratsun is Golden by comparison. But I suppose those big sites are burdened with the handicap of Professional Managers (who never seem to think of the actual site users). Len

    GROSS POLLUTER - Failed Cali Smog test

    Roadster-ka is correct - unplugging the 12V to the choke will keep it closed, not open. However if you loosen the 3 screws on the plastic choke spring cover, I think you should be able to rotate the cover to the point there is virtually no spring pressure trying to push the choke closed. My memory is that the choke butterfly is offset relative to the choke shaft so that it will stay wide open even if the cover and spring are entirely removed from the carb. But I'm not absolutely sure what happens at different manifold vacuum conditions. I think any time I've wanted to be sure of no-choke, I hay wired it open. I can't resist doing my possible loose small venturi rant once again. In the second pic in you post #11, I can see the venturis (one in each of the two carb barrels) down in the gloom of the carb throats. Just bellow the open choke butterfly for the primary barrel. If you haven't done so already, reach down with needle-nose pliers or a mini-seal pick and make sure neither of these is at all loose. Maybe just prying with a screw driver will be enough to get a wiggle if either is loose. The reason I'm obsesso about this is two of my three Datsuns came with carbs with this style small venturi holder and both had worked loose. Others on Ratsun have posted they have had this part come loose. My theory (which may be total nonsense) is if the venturi holder is loose, it can pull raw gas out of the one end where there is an O-ring, rather than through the tiny hole out at the small venturi where the gas is supposed to come out and be atomized as it is sucked down the carb throat. If your venturi holders are tight, that is wonderful. Ignore the prior rant. You mentioned the EGR valve being old. I vaguely remember something about a stuck EGR being not a good thing but I have no idea what happens if the thing is non-functioning. Maybe nothing that will matter in a smog test. I've pulled off EGR valves that were gunky with carbon so maybe they can be cleaned rather than replaced. Len

    GROSS POLLUTER - Failed Cali Smog test

    It sounds to me like your choke isn't adjusted correctly; that it is holding the choke butterfly on too hard and/or for too long a time. The way to adjust this is loosen (don't remove) the three screws that hold the plastic choke spring cover and SLIGHTLY rotate the cover so you can feel less spring pressure pushing the choke butterfly closed. There shouldn't be much spring pressure, just enough to close the butterfly when the engine is cold. I suppose this time of year in Cali you don't need much spring pressure. There is always a chance someone has installed the plastic cover wrong and it will need to be removed and reset. But only worry about this if you can't lessen the spring pressure by rotating the plastic cover. Another thing to check is that you have 12 volt power at the terminal on the choke spring cover with the engine running (not just with the key on). This power is what heats the choke spring and lets the spring gradually release pressure on the butterfly. This 12V power come from the alternator circuit and only when the alt is turning, hence the running engine. Len

    GROSS POLLUTER - Failed Cali Smog test

    I'll assume you checked the fuel level in the float bowl by looking through the round window on the front of the bowl. If the float isn't adjusted to give the correct fuel level in the bowl, that could flood the carb. Take the air cleaner off and look down the carb throats. If this is a Cali smog carb, the small venturi (round ring thingy) will be supported by a tapered bar across the throat. Grab onto this bar with your fingers or needle nose pliers and make sure there isn't ANY movement in any direction of the bar/venturi unit. On one end of this bar there is an O-ring between it and the carb body. If this O-ring is bad or the bar is loose so the O-ring doesn't seal, it may cause gas to be sucked down the carb throat. When I got my F10, this bar/venturi had come completely loose from the carb body and was keeping the choke butterfly from opening more than a little bit. Now that was running rich! Len
  5. According to this Flickr blog Q&A, there aren't going to be any real changes in Flickr at least for the time being: https://blog.flickr.net/en/2018/04/20/together-smugmug-flickr-faq/ Who knows what may happen in the future? I suppose Flickr could go to all paid accounts but that is true of any of the free pics hosting services. It could be they are all watching how well the changes to Photobucket worked. If a lot of users sent Photobucket money rather than leaving Photobucket, then other companies may think doing the same is a good business model. If Photobucket lost thousands of users then other companies may learn from that mistake. It looks like the only thing really different for now is as of May 25, unless you tell Flickr you don't accept their new Terms of Service, you are agreeing to those Terms. Any time you get a credit card or new phone plan or have any dealing with a corporation, you are either going to agree with their Terms of Service (probably without reading them. I skimmed the Flickr Terms this morning but my eyes started glazing over) or not use their service. That is reality today. It briefly crossed my mind to attempt to include a photo from my Flickr account in this post just to see if I can do it. My experience in the past is every time I try to do so, Flickr has done an "improvement" and I'm unable to find the URL of the pic to post. But I don't think I want to risk that level of frustration so early in the day. Maybe later. Len

    This page may help in rebuilding your dizzy: http://web.archive.org/web/20050308082501/home.att.net/~jason510/Dizzy_FAQ.htm Go down to "Disassembly" and there is a link over to another rebuild page. "The screw that attaches the vacuum canister actuating rod only threads into the moveable advance plate, the special screw has a unthreaded end just sticks into the hole of the actuating rod." is important if you swap your vacuum advance. It was just dumb luck I noticed this special screw when I change my advance canister. Len

    My '76 710 Goon

    I have a partial excuse. Although my dad was born in Missouri, when he was about 16 the family moved to Canada and he lived there until he was into his late 20s (then for some unknown reason most of them migrated to Spokane). So I may have a slight genetic imprint for being Canadian-like. Which I'm kind of proud of and explains some of my odder tendencies. :lol: Len

    My '76 710 Goon

    Okay, that is great information. I thought of trying a cutoff wheel in my die grinder but it quit on me the last time I used it. My angle grinder is still working though. I have a hand bead breaker that takes care of that part of the operation. Last summer I tried to take a tire off a 14" steely with my hand tire irons and couldn't do it. I think I'm getting too weak to be messing with something like that. Even when I was younger and fighting a tire with hand irons I would think "Why am I doing this? The local garage has a machine for changing tires." I guess I enjoy the challenge or something. Len

    Do you have a good method for cutting tires off of wheels? Seems the few times I've tried it I run afoul of steel cord and give up. Chop saw? Propane weed burner torch? Or something even more loud and dangerous? :lol: Len

    200sx axle in a 510 Wagon

    Okay, I think I got it now. So I can go back to feeling bad although the reality is if I'd grabbed that rear end it would be taking up space in my shed along with everything else I got off that SX. At least I know I didn't imagine seeing rear discs on it. Len

    200sx axle in a 510 Wagon

    For several years I've felt bad that I was too lazy to pull the rear end when I parted out that '81 200SX.Somehow I've always pictured it as having rear discs. I finally realize I didn't bother to get it because it had drum brakes, so why bother? I feel a lot better now! Len

    200sx axle in a 510 Wagon

    According to this site: https://www.cars.com/reviews/the-morning-call-and-mcallcoms-view-1420689106509/ the 1984 200SX "The rear has a solid axle and a four-link coil-spring suspension, a somewhat dated system but very effective." unless it is the turbo version which "For reasons best known only to Nissan, the rear suspension of the turbocharged version is fully independent and features semi-trailering arms, coil springs and gas-filled shock absorbers". I can't guarantee the accuracy of that information but my '79 200SX has a solid rear end with drum brakes and I parted out a '81 SX a few years ago which also had a solid rear end (and I think rear disc brakes) so it seems possible the third generation S12 200SX was also solid. My '79 SX has rear leaf springs so my guess is it may be the easiest to mount to a 510 with leafs. The four-link system on the '84 solid axle would possibly need spring mounting points welded on but I don't know that for sure. Len

    What are you listening to???

    So I'm watching Leo a few nights ago with a smile on my face because Leo is above all else fun and entertaining. My wife walks in and asks WTF?(although she doesn't use that sort of language). So I invite her to expand her musical horizons and restart the vid: Vid finishes and she asks about the song. I say something about Adele cover and get a blank look. So I search up the original Adele song and cheesy "Modern Romances" vid and play that (and I even like Adele's voice although her style isn't my fav. I'm thinking she will get a lot better with time). Anyway, my wife says "That was MUCH BETTER." I can only reply it depends on your definition of "better". Occasionally I will play something Karen says she likes. But usually her tone of voice leads me to suspect she is trying to be polite. More often she comments on my music with "that was WEIRD" which I take as a compliment. Len

    I'm Definitely in the South Now

    I ended up living in northern VA in the late 1970s. Being from Washington state, when I first saw Lee-Jackson Day on a calendar my eyebrows went up a bit. I'm mildly surprised it is still on the calendars but VA is noted for being really big on history. The joke is "How many Virginians does it take to change a light bulb?" - "Three. One to change the bulb and two to talk about the glories of the departed bulb." I liked living there except for the hideous humidity in the summer. I was living in a single-wide trailer with no air conditioning. I hope you fare better in your accommodations. I remember having tools rust even when kept indoors if they weren't oiled. The lightening bugs in the summer almost make up for the humidity - almost. My wife and I met at the horse farm in VA where we were working. She was born and raised in Leesburg, VA. She has stuck with me all these years which still puzzles and amazes me. Her moving from a beautiful state like VA to desolate eastern WA is something I don't understand quite. I was born here so desolate is what I'm comfortable with. Too many trees make me nervous! Len
  15. Be aware here are two little steel check balls - one under the accelerator pump and the second under a brass plug near the accelerator pump (carb top must be off to see this plug). If you aren't watching for these when you tear down the carb, either can escape into the world and you may not ever know they were in the carb. Then your accelerator pump won't work which is maddening. Make sure your small venturis (I think that is the correct name. The round ring thingy on a stalk in the center of each of the carb barrels) are tight in the carb body. There were two version of these. One used screws from the top down into the carb body to hold the venturi assembly in place. The other used a single set screw through the side of the carb body to hold the venturi. I believe was a Cali smog carb but of course some of those may have escaped from Cali over the years. This style has been known to loosen up over time and cause problems. Hopefully you will have the screws-from-the-top version and have nothing to worry about. Len
