freaky510 Posted August 30, 2008 Report Share Posted August 30, 2008 So i am trying out some s/u's i bought a while back. And i lost the little copper fitting that holds the fuel line from the float to the carb.So after looking for it in the space between the boards on my back deck i have decide to just change that old ass line anyway.I was just wondering what can be done or where i could find some Quick i know i could go to a local hardware store but i was thinking like a cute little braided line but the connection is the trick.

yello620 Posted August 31, 2008 Report Share Posted August 31, 2008 Is it just a copper compression washer? Those are available at the local hardware store. Maybe that will get you back on the road while you source the cool parts or hear back from Z therapy. Jason Quote Link to comment
freaky510 Posted August 31, 2008 Author Report Share Posted August 31, 2008 went to lowes and home depot they dont have anything that small so i think iam going to put up a ad in parts wanted and try to find myself a good set of carbs. I have a lead on 1 set but i dont know when that going to happen i guess someone in the Tacoma area has some parts for sale and a buddy was going to hook me up. Yea it kind of pisses me off i bought my carbs off the forum they sid they were good what LIES those damn things leaked gas out off every possible place they could leak and all the fluid in the top leaked out of 1 so i will have to save them for parts i guess so thank you for all your help on this matter so if anyone reads this please let continue in parts wanted Freaky510 Quote Link to comment
slodat Posted August 31, 2008 Report Share Posted August 31, 2008 The gaskets are $2 ea from Z therapy. There are only 4 gaskets. It's very possible they are just dried out if the guy had them sitting around for a long time on a shelf or something. I question if the SU's you have are actually unusable. You might save yourself some $$ by getting the gaskets and a few cans of carb cleaner. That's what I did with mine. Mikey got them running great! Quote Link to comment
freaky510 Posted August 31, 2008 Author Report Share Posted August 31, 2008 THEY LOOK PRETTY SHITY i wish i would have looked them over a little better in the first place i dont think i would have bought them but it was getting late and i wanted to get back home i had to drive down to portland to get them and then dude was an hour late i was tired and hungry and wanted the hell out of portland what pisses me off the most is i hooked that guy up with parts for his truck imean i gave this guy alot of good stuff and some cash so i would feel a little more comfy with a diffrent set i have intakes just looking for some good carbs please see parts wanted post or we can continue here Quote Link to comment

zerow Posted August 31, 2008 Report Share Posted August 31, 2008 My fellow SU brother, I hate to break this to you, but those are not Nissan Hitachi SUs, at all. Period. ztherapy might be able to help, but it is likely you will need the help and technical assistance from a British/Volvo SU shop. I know of one: http://www.aptfast.com The fabrication of the SU manifold is commendable, but, far from Nissan as well. If you need some good shots of some Nissan SUs, hit me up, or check out this thread: http://forum.ratsun.net/showthread.php?t=5347, 9th picture down. I have only read about this conversion, never seen it before. (edit) It would appear that these are more British than Swedish. Still HS-style carbs (lemme ask: is the opening at the front of the carb 1 1/2" (HS4) or 1 3/4" (HS6)??) The float bowl tops lean me to say MGB, but, once again, I am only basing this on pictures shown. Quote Link to comment
ppeters914 Posted August 31, 2008 Report Share Posted August 31, 2008 Do it the right way and get in touch with Steve at ZTherapy.com,he is the SU guru. i have a call into them no reply yet Probably because it's the Labor Day Weekend. My guess they won't be answering any phones/emails until Tuesday. Quote Link to comment
freaky510 Posted September 1, 2008 Author Report Share Posted September 1, 2008 well damn i dont know what to say except iam feeling a little raw right now :Dyea it sucks being an idiot and it cost alot of money too!!! Quote Link to comment
zerow Posted September 1, 2008 Report Share Posted September 1, 2008 well damn i dont know what to say except iam feeling a little raw right now :Dyea it sucks being an idiot and it cost alot of money too!!! You didn't know. Don't beat yourself up over it. There are ways to make them work, just don't know how much it will cost. I am more than sure places like aptfast have rebuild kits, its a matter of calling them on Tuesday. I always (always, always...) look for the Hitachi company logo whenever I deal with the fuel system on my Datsun. Thats as OEM from the manufacturere that you can get. Let me know if you need any help. :o Quote Link to comment

freaky510 Posted September 1, 2008 Author Report Share Posted September 1, 2008 i not beating myself up i just want to drive my datsun it been like 2 months since i did more than a mile in it. i move it around the house a few times start it every other day and then it sits waiting to get beat on. i really want to beat the sob for not being what i consider a datsun guy. bbut hey we live and we learn well some of us do :lol: Quote Link to comment
slodat Posted September 1, 2008 Report Share Posted September 1, 2008 I bought my first 510 ('69 wagon, mklotz has it now) from a professed Datsun guy. There were warning signs all over the place, and I noticed them. I was without transportation and had limited cash flow. So, I bought it on the guys word about all the questions I asked. It was all little crap. That didn't stop it from barely making it home and not leaving the house running again in the as purchased form. I've been a car/motorcycle guy since birth. The Dattos are different then what I was used to (in a great way). So, I had to learn them. That cost me the better part of a couple grand before it was said and done. I didn't have any forums or friends familiar with them at the time. So, I bought a lot of the basics at full retail to get it running. Once I did that I got it running good. Knowing what I know now, I can do the same for next to nothing in comparison. Chalk it up to experience is what I did. I also fell in love with dattos in the process... Quote Link to comment

Phlebmaster Posted October 3, 2008 Report Share Posted October 3, 2008 (edited) You will definately need bigger lash pads for that cam. That is one of the reasons I never installed it on my truck. The cam I have now came with everything, including some very tall lash pads. Edited October 3, 2008 by Phlebmaster Quote Link to comment

banzai510(hainz) Posted October 18, 2008 Report Share Posted October 18, 2008 regrind cams need bigger lash bads New one That I notice dont need as big lash pads. I went with the Nissan retainers as I bought a cam from Schneider their retainers were kust a little tall rimmed with the cam set up they gave me so I used a Delta regrind cam an but bigger lash pads to compensate.anout 190-200 range If I remember right I latter used that Schneider cam with the nissan retaineras and about 160 lash pads Nissan sell the retainers in different sizes so maybe th Isky and others only make one size set. Could always but the retainer on t adisk sander to lower the rim abit. just make sure the rocker wear is in the center Quote Link to comment
