if you're adding fuel (in what way?) and it's getting better what makes you think it's not a fuel related problem. tip in can be a monster if the carb is out of whack.

james I have had 3 different carbs on it from a 750 proform based carb to 1050 dom. have a 950 quickfuel on it now. have tried just about every squirter cam combo there is. now we are dealing with mine shaft conditions also. I notice when air is worse it does seem better. I tried the quickfuel as set up first. this set up works fine on a few other cars I know with a stroker combo.

Are you talking about when you stand on it it stumbles, or just tipping into it driving around?

Does it have a decent loose converter in it?

The only other thing that might be causing it is timing? Is the timing locked out in the distributor?

are you running a carb spacer on that intake with the 4150 carbs?

The converter is plenty loose enough for this problem, I was thinking if it was REALLY tight. I thought you were talking about "tip in" like for drivability just crusing around.

Why the heck are you trying to go from idle to WOT with a combo like this anyway?!

At idle RPM, when you slam the throttle blades open it's got no air speed at all, which means no fuel, which means bog. It's gonna need A LOT of squirter to cover that big of a hole...

yea I would say so 50cc pumps with 50 squirters is not enough it's a footbrake car. and sometimes you can't use a 2 step thats why you need a good transistion.

What's your total timing? I agree with some others on here. Small cubic inches, big heads and intake and that's causing the issues you're describing. I'd consider locking in the timing at 35 and either having a the starter switch separate from the ignition or running an ignition with a start retard.

yep thats an option, going to jack it up some more

Do all three carbs have rear jet extensions? Does it bog anytime you open the secondary or only when foot braking it and then hitting the throttle to WOT? I have had carbs. that would bog when to rich, with to much squirter and also when to lean and to small of squirters Keep expermenting and let us know what you find. BTW, I have never tumed a race car that was racing in weather that had more then 40 % humidity except just before and right after a thunderstorm
