I am currently running a 440 Rupp with 39.5 Mikunis. I am running 680 main jets which is giving me almost perfect plug readings and 1/4" of piston wash. Is there anyway that I can get a jet made between a 680 and 660 ??? I think that it would be way lean with a 660. Any opinions or suggestions ?????

Re: Is this a dumb idea ??
if you are not concerned about the original look of the carbs then i would suggest our multi adjustable clicker power jet you can fine tune your main cuircit to very small levels in between main sizes.

Re: Is this a dumb idea ??
What company are you associated with ?? How much is it and how hard is it to hook up ?? These are the original carbs that have been bored out. They still have that adjustable main jet on the float bowls that were made in the 70's. I always keep them all the way open as I don't really trust them that much. THANKS
