And I have also pulled carb top after it shut off, without any additional cranking and fuel level in bowl appears to be correct. Gonna swap dist this afternoon so we shall see. Whata ya gonna do?
Do you have a vacuum gauge? Reason I ask is you should measure vacuum from a cold engine untils it dies. If you're losing vacuum when it get to operating temp. that''ll eliminate the ignition and fuel systems. I've had a couple cars with dual wall pipe that had the inner wall "swell" and block off the exhaust system. They would run good cold then slowly lose rpm \ power. We could only diagnose this with a vacuum gauge. I've seen a car do it with a blocked cat. converter too. Act like a bad fuel filter or weak coil but the darn thing just couldn't breathe! It's easy to check too!
