    it is, but comes right up to the top of travel on the second push.

    Good way to store an emergency set of points and condenser. I went through all the boxes of parts that came with the truck........6 pos distributors but one is a D4k9-08 matchbox with base. I believe it has issues though as the center rotor at times catches the metal points on the outside as you spin it. Shaft is not super loose but obviously has some movement. Does anybody rebuild these things? Can the module be easily tested and are they available if it is bad? Thanks for the tips on the brakes, they come right up and hold on the second stab. I thought they were adjusted ok as they all had some drag but i will go ahead and re-adjust a bit tighter.

    Thanks Wayne, Don't suppose you would know where i can find a matchbox and coil in good condition? This one does work but i would like to find a matchbox and keep this for an emergency spare.

    Got the timing dialed in and ordered some hoses and a plug to fix the currently dysfunctional pcv system. Curious.... My dizzy is dual point but one side is not connected to any thing, so it is effectively single point. Can anyone tell me how this is SUPPOSED to be connected/wired?

    I disconnected the vac advance and put a timing light on it. I have a pulley with 6 notches. Looking from front of engine left to right, small notch, large notch, then 4 small notches. I assume 5 after, tdc, 5,10,15,20 btdc? If that it the case my distributor runs out of adjustment at 5 btdc. Either i have the wrong pulley or the wrong dizzy / mount or the pulley makes no sense to me. There is a pcv valve on the breather hose, just could not see it. The hose is completely split so it does nothing anyway, just acting as a plug. Going to have to fab a reducer pipe to get that back together.

    Oh yeah, idle is unpredictable.

    Well that is just lovely. My pcv is sticking vertical where the threaded vac fitting is in your pic. the crankcase vent is connected to the manifold directly with no valve! NOT GOOD.

    Finally got a minute to work on things a bit. Here is what i have learned so far: 1) Kingpins are beyond gone! i can gab both front wheels and pull the bottom of either out well over an inch. 2) vac port on carb has been plugged with some kind of epoxy, working on this tomorrow. 3) runs good but falls on its face when taking off in first, maybe related to vac advance being wrong? 4) adjusted clutch, much better but still engages at the top of the pedal travel. 5) all the joints up front have no dust seals remaining and zerks are seized so no new grease going in till they are replaced. 6) brakes adjusted well but pedal is soft on the first hit, second time they are right at the top. Thinking air or a bad wheel cylinder. 7) pcv valve is connected to...nothing, what appears to be a vent tube coming from the block is attached directly to the intake manifold. Anybody now where i can find a diagram of how this is supposed to be? All the air pump stuff is gone. Picked up my new seat and a window regulator from Wayno yesterday, 9 hours of driving but it was worth it. Also ordered all new window seals from Thailand, that was all i could find.

    With a huge thank you to Wayno on here, it looks like i will be picking up a seat (and possibly a few other goodies) on Tuesday. Found an air cleaner in Oregon on craigslist. Hoping to get time later in the week to pull the carb and see if i can drill the ported vacuum open. At the moment, we have a fire in the wood stove, it is snowing, there is lot's of really really yummy stuff to snack on and i am not going to do diddly.

    that's the spot, but just a dimple in my carb base, plugged solid, no nipple no threads. looks like it was cast that way, or somebody did a nice job of plugging it to make it look as cast. I will pull the carb soon and if the throttle base is in fact drilled at the throttle plates and someone just plugged the outside, i can throw it on the mill and drill it out. I will also check the shafts, if they are loose, maybe i can turn some bushings providing the base plate has room to bore and sleeve. I have that air filter lid and support bracket but no base. Thanks for the pics.

    No nipple there whatsoever, just a dimple in the casting maybe .030" deep.

    Yep air cleaner housing is a hacked up joke, already have some leads on parts though, lot's of good folks here. No ported vacuum on the carb, there is a dimple in the base, but was either not originally machined or has been plugged, hard to tell. I did get another carb with the truck but it is in 3 different ziplocks, i do see a ported vacuum nipple in the throttle plate for that one. Question: are the original Hitachi carbs worth going down the rabbit hole, or would i do better to go weber and put my energy into making an adapter to use the stock air cleaner?

    I hear ya but there does not seem to be a ported vacuum nipple on this carb,......new challenge.

    Yes, i do have an air cleaner cover with the manual heat riser lever that came with the truck, but i have no base. That is the first item on my list if i can find one. I also noticed it was manifold vacuum but at a glance i did not see the ported vacuum nipple, lots going on and i just get a minute or two here and there today. Carb:

    Ok, got the run on sorted, idle too high. There is something going on with the cable or carb though, it likes to hold up a bit and i have to blip it to get a drop to proper idle. I will get it fully sorted soon, the upcoming holiday is sucking up alot of what would normally be free time. Engine # matches tag on firewall. Only real dent, passenger rear corner. Pics:
