I 'm pretty sure I know the problem it's my valves. But I messed up big time with putting too much Sea Foam in the carb. Of course it smoked like a chainsmoker in a cage of bobcats. White smoke, then diesel looking smoke then died. for good measure I poured the rest of the can into 7 gallons of gas. Got it started still not right so as long as the old trucks were on gasoline drugs put about a 1/4 cup of de ice in it still not well went for broke and put octane booster and some Marvel etc. Hey, maybe i'm a warlock mixing up a brew. Took two times of draining tank and sloshing out then clean. Put high test in and after 1 1/2 hours of fast idle I got it. Running as much of the high test out then refill with white gas. Oh buy the way the mix of solvents and the other additives looked like baby poo. Here is the question? why does it still have a valve burp about every 40 seconds? Every valve was burping initially but know only one. Valves adjusted correctly, I know the head probably looks like black fur, valves have 31,000 on them. Should I just keep running it or not worry and slowly get it up to 45 or 50 mph. Doc
