Having a nightmare setting the timing on my AZDart. It's a 225, Carter BBS carb. It's a 1966 225 engine (casting # 2463439-22). Mopar electronic ignition. It was running, though badly when I got the carb and choke into "pretty good" shape. I found the vacuum advance diaphragm leaking, so I bought an electronic ignition conversion kit from Mancini Racing. Installed the distributor, got out the timing light, NO START! engine kicks back, but will not start.

OK, lets find the timing mark on the crank pulley. No timing mark on the pulley, only a few pencil/pen markings. OK lets find T.D.C. and start from scratch.

(My buddy has a unique T.C. finder, a tube mounted to an old sparkplug body, with a small balloon on the end of the tube. install device in #1 sparkplug hole, rotate the engine 'til the balloon inflates - bingo! T.D.C. on compression stroke)

The marks on the crank pulley are near the marks on the timing pointer, so we clean the old markings off and put our own mark. Tried to set the timing and finally found a setting that allows the engine to start & run but the distributor had to be turned further than the hold down screw allowed. Reset the plate on the bottom of the dizzy, moved the plug wires one tower clockwise, reinstalled the unit and turned it so that the distributor gear was a notch, then two notches further advanced. No JOY! cannot turn the dizzy far enough clockwise to get the engine to start because the nipple on the vacuum advance can hits a red bracket of some kind attached to the inner fender.

Finally called it a night Your experience, opinions and/or wild a$$ guesses are sought. Thank you all, and good night.

My original issue, boiled down was:

Cannot turn the dizzy far enough clockwise to get the engine to start because the nipple on the vacuum advance can hits a red bracket of some kind attached to the inner fender.

MAJOR brain fart!! Neither of us has much previous experience with /6s. V8s don't have clearance issues like I touched on in my first post (the red bracket).
What we completely missed is that the first step HAS to be rotating the dist body so that the vac can has plenty of room to move wherever it needs to.

(OK, folks, you can quit the snickering now! I finally figured it out and the rest of you were kind enough to not point out my ignorance.)

Once the dizzy can be turned enough, the rest of the setup is a piece of cake.

We didn't work on it today, Don. But when I thought about it some more, I realized that the vacuum can was not the real problem. There's a plate that bolts to the underside of the distributor, with a slot that the timing lock bolt goes through.

When we got the engine as smooth as we could, our timing mark was just about straight up, quite a way away from the tab on the engine and we had the lock bolt out, because that slot wouldn't let us turn the dist far enough.

A response I got on another forum said that: "Some aftermarket dist. pick-ups are wired backwards and cause the ign. to fire 20-30 degrees off from the correct phasing."

Obviously, more investigation is needed (dammit!)
