Are you sure its a mechanical distributor? Or is it aftermarket? Al b18or b20 distributors are vucuum controled. Even the one of the b20e injection motors.

So im having issues getting it running properly again. I believe I sorted out an issue I had with the alternator, but still having major problems with the carbs, timing, etc. It has a tough time starting and then it idles rough and if given any throttle it backfires and bogs down. Ive been through this before, but its taking me some time to get it diagnosed.

Chech that you dont have air leaks in your manifold. If you have one, the car cant idle stationairy. And the throthle response iisn"t that good.

From time to time i spray a can of brakecleaner round my manifold or vacuuumlines (with a running engine), if the rpm changes you have an airleak.

Air leaks in the manifold are very comon for this type of engine.

Also its very common that the su"s are worn out and wont be able to set properly. You can buy revision sets with the right needles.

wow i can't believe I've missed this build this long, I just sat and read all 22 pages of your build. I love everything about it, all of the attention to detail and the general theme is perfectly executed.

Might be bad gas?

I freaking love the wheels man, wish my car was at this level... maybe someday

Wheels are back from powdercoat. Came out really nice! Drove the car down the street and it ran better than it ever had for two glorious minutes and then began to struggle. I limped it home a couple of blocks and now the head scratching begins..

Hey Keith - love the build! I've got a 66' i'm looking to bag - I've gone through the photos and printed a few out to work with a local fabricator for the mounts. I was wondering if you can recall the dimensions for the front and back mounts? Any pictures of the rear? Many thanks!

Hmm is there a balance tube between your carbs? If so are you syncing them with it unhooked?

there isnt a balance tube between the carbs. Im starting to lean more towards the spark side of things. The carbs seem to be set correctly. While doing the timing again tonight, it was barely starting and running horribly. It would stumble and even the timing light was working intermittently

diagnostics are THE WORST!!! i'm trying to get a day job as a mechanic with the hopes of improving my diagnostic skills, among the other things I will learn.

keep us updated man

Is it a vacuum advance distributor?

Sounds very timing/carb sync related. Throw a timing light on it shouldn't be to hard to get it running decent.

I almost got things running decently and with carb adjustments and then I turned to the timing which didnt seem to be too far off, but needed to be set. Set the timing and it seemed to help for a little bit and then it got worse. Ive been working with the carbs and not seeming to get anywhere. Keep thinking something's up on the distributor side
