Bain bent its intake valves several months ago. I have my own theory of lacquered varnished gas as the cause. I procured a nice used ebay head for substitution. But I believe my timing maybe off one tooth. Hard to start, but once started becomes a one kick machine. Is there a way to verify correct cam chain timing, by looking at the righthand side advance plate? I really don't relish pulling the motor and head again. I can't give it any type of fuel when its cold. No, choke, don't touch the throttle until it sputters to life. Which is a spit and stutter painfully slow event. Sounds like Bain has been smoking a pack a day for ages... Once running it pulls very well. Roll off the throttle and popping occurs in the exhaust...The clock had 3000 miles on it when I received it. The engine was never opened by anyone. Points, which I replaced looked original. The jetting is stock. Plugs were new. The advance rod is free. I just ran it 200 miles and two tanks of fuel. Looking for directions to travel...I'll get some timing light videos for reference tomorrow.
