Author Topic:   Carburetor hesitation
posted October 17, 2001 03:49 PM
We chased an off idle hesitation all season long this year. We have been able to get it better, but the motor still hesitates on starts and restarts.
We have changed main jets, adjusted idle circuitry, and changed accelerater pump cams, to no avail.

this is an alcohol burning motor

Can someone offer some insight

I currently Have a 750 carb built by Bill Mitchell. The motor is a 406 running on alcohol. I dont think the carb is to big for the motor. The car is a 2900 lb Limited late model\Sportsman

I have heard alot about willy's carbs though,

Where can I get some more info,
Phone Number, Prices, Catalog, Web Site, Location Dealers Etc.

Thanks for the help

What kind of fuel regulater are you running? The barrel valve type or an adjustable ***** valve type? I know that the adjustable ***** type's have a jets to restrict the flow of the fuel back to the tank. Also how much fuel pressure are you running? At an idle I run no pressure, than at full throttle it jumps to 6psi. I run a mild 360 with alchol.
