Ok guys... Here is an update and I'm left more puzzled now than ever!
I called up a local guy who runs his now business of restoring classic carburetors. He just happened to be driving near me so he stopped by and spent 2 hours looking everything over with me. His conclusion was that the Rochester B carburetor I have is good and working as it should.
Here's the problem.... We could not get it to start. After trying for a few minutes, I showed him the fuel sitting in a pool down in the intake by opening the throttle and looking through the carburetor. We pulled some plugs and the plugs are dry. Shouldn't they be soaked in gas after filling the intake with gas???
At this point we checked the ignition and initial timing all of which checked out ok. Pugs are firing. Compression checks out to be good on all six cylinder. Valves have clearance at the rockers.
We put a vacuum gauge on the port of the intake and were getting NO VACUUM reading at all while turning the engine over!!!! The only way we could get any vacuum when turning the engine over was to cover the top of the carburetor by hand. It seems like the engine is not sucking the fuel in at ALL. The guy put his thumb over one of the plug holes while i turned it over and said it was blowing out but never did it try to suck in.
Could the problem be somewhere between the intake/exhaust OR between the intake and the engine???? When he left, he assured me that the carburetor is not my problem right now! But he left confused and said he would be thinking about this all day!
Should I pull the intake/exhaust manifolds off and check for any issues there????
Has anyone else ever experienced an issue like this?
*Reminder: the engine is a 235 with the 848 head.
