How do you adjust how much fuel my carb puts into my engine. i have a autolite off a 390 on my 351w engine and it is running very rich. is there a way i can slow down my gas input on that carb. i can not seem to find it.

 

One way is to slightly lower the float level, but that will only get you so far. The real solution is to change jets. Unfortunately, I believe the only reliable source for Autolite jets is Pony Carbs.
