Monaco stutters when I floor it...
Hi all, I have been driving my dodge for about four months and everything seems to be working well except when I floor it (still getting over the lead foot) the engine cuts out just a bit at first then takes off like a rocket. Any ideas on what might cause this and recomendations on how to resolve it would be greatly appreciated.. Thanks

My 440 does the same thing with the 750 carter on it its way more noticable when i have a rolling start and then floor it. I have read that because of the mechanical secondarys with no secondary accelerator pump and that it initially falls on its face because of a extremely lean situation once you get vacume back the engine starts sucking gas and takes off. I have read that a person can modify the weights on the secondary air plates(kind of like a choke for the secondary's i cant think of the technical name) to correct this problem but i have never done it. You could also try to change the nozzel size on the accelerator pump to get that volume of gas that it squirts in there a little faster

It usually has something to do with fuel delivery, and "may" be the accelerator pump, or it may not... Could be as simple as an incorrect air/fuel mixture, vacuum leak, wrong size power valve, a dirty or clogged fuel circuit, etc.
A timing issue could be at fault too, but I don't think that's as common, unless the advance curve is way off.
I had VERY slight hesitation when the engine was cold. In my case it was too big a power valve and adding a 4-bore, 1" spacer under the carb helped a lot. (Single plane/open plenum manifold.)
