Well finally got to mess around with the car a little the other day. As suggested I started looking for vacuum leaks and I think I found the problem. Kinda wierd because I had just put all new vacuum lines in but the one from the brake booster and the back of the carb were bulged out and not...

will do, im not sure if i will get to it till next week though, going out of town for the holiday.

later trailbeast thanks for the help!

I have not done a compression check only because I had 22-25in in vacuum at idle (if memory serves) and have no burning oil, but it could be worth buying a comp tester and trying it. So, factory dizzys are bad news, I was told that you could run one without vacuum because the vacuum was added...

ok bear with me, so hook up the light and make sure at idle its 12-15 then give it throttle while watching the timing mark to see when it starts advancing and where it tops out? Is it common to have to re-curve a stock dizzy?

Maybe a slack timing chain? or off a tooth? It really has me baffled, no matter what adjustment I make it stays the same, ive tryed 3 carbs, two dizzys, all kinds of air/fuel adjustments, timing adjustments, the stumble is still there.

good thought, i did try that though, currently I dont even have the vacuum advance attached, i detached it and advanced the timing (as it is now) and it still does it. Before I did that though, I did try and back the timing off and advance it both with the original dizzy and a new one, same deal.

yes, the accelerator pump is squirting emeadiatly and steadily through the whole stroke. The car does have power brakes which are very touch in the morning lol. I have a large vacuum purt at the rear of the carb which i have a t-fitting going to the brakes and the pcv

Oh I thought maybe the ratio would bog it down lol, shooting in the dark lol. I thought maybe vacuum leak but I sprayed carb cleaner around the intake and carb and the rpms never ramped up. I could try it again though

Thats a good idea on the grounds, the stumble is there day or night, the lights were just an indication to me that the output from the alternator might be low and if so the voltage to the MSD would be low. I dont even know if low voltage from the MSD would cause the stumble but it was a though I...

Hi all, I have a 73 scamp with a 360 from a van, airgap intake, quickfuel carb, headman headers, msd 6al. I have had a stumble issue at low rpm. I had a quickfuell 600 and now a 750, messed with both, new dizzy, messed with timing (I have even taken the vacuum advance off and increased my total...

I have a whole center grille with lenses (i just converted the front end to 70-72 on mine) for a reasonable price, it will get it out of my garage lol

Youre right, any motor depends on the heads/cam, I gotta start researching small block heads lol

Just went threw your whole build, love it! you do some awesome work! I was debating on taking out my smallblock and going to a bick block but I think you have just inspired me to keep it!

wow, 1300, i figured expensive but that is rediculous for a carb!
