Rochester 2-Jet: Starting Problems
I have a 1986 CJ-7 running a 258 with a Rochester 2-Jet carb on it. I've had it for about 5 years now, and the PO had let it sit for about 18 months before that. The carb has always run a bit rough, so I finally semi-tore it down last night to give it a thorough cleaning - took off the top of the carb, removed all the parts I could like jets & idle screws to clean, lots of carb spray, etc., even filled the bowl with Seafoam and let it sit for 10 mins before start up. When it restarted (after all of the smoke from the sea foam cleared) it seemed to run as good as it ever has! Even set the idle needle screw mix deals (had them at 3 turns out as starting point - engine RPM's dropped at 1.5 turns in so turned them back out another 1.5 turns. That was the best imitation I could do of the few instructions I could find on-line to set those)
Drove it today and it ran even better. As soon as I stopped somewhere and came back out to do a warm re-start, it did not want to start. It took a good 5-10 cranks and had to have pedal to the floor to get it to start. Took the air cleaner off to confirm that gas was squirting into carb when I pushed on the throttle arm, so that seems okay.
For complete disclosure, I also changed Fuel Filter & air filter last night, and put in new spark plugs about a week ago. Engine has an HEI on it.
Any ideas on what I might have done wrong? I'm considering just buying a carb rebuild kit and fully tearing it down to be on the safe side, unless others have a better suggestion?
