Default Re: Any ideas? Still Rich!

Looking at your intake gasket - sure looks like a lot of core shift in the intake ports - wonder if you were sucking out into the one in the rear (where you have oil in the bolt hole as well?). I'd probably use a bit of 'gaskacinch' on the gasket and intake surfaces.

For you to have that much fuel in the intake ports, then obviously there is an excess of fuel coming into the motor. If you haven't rebuilt the carbs, then I would at least check the PV's and gaskets. Sounds like you're not flooding out the carbs will fuel pressure.

Questions: Did it used to run well and then this started happening? Or was it like this from get-go? Also, what plugs are you running?

Lastly, what are the specs on the rest of the motor? I can't see two 97's with .042 jets being that rich - even on a stock cubic inch motor.
