I was told by most that only 37 mm chokes should be used or you woud have drivability problems around town. I have not found that at all and I think that is why most have trouble with fouling. 37's are for small blocks. My car runs beter now than it ever did with the Holley set up but I can tune it even better, that is the advantage of the webers. I find it fun so it is no big deal. An LM1 is a must to get it correct just as with any system. I may send mine off to have the third progression hole drilled, this seems to help also.
