Well I think the distributor is either broke or not working right. I cant ever find the mark with the light. So I adjust by ear, get it idling good and once I put a load on it, it begans to miss and it comes thru the exhaust. So I add alil and then it misses and comes thru the carb. I cant find a happy medium and then it over heated, nothing crazy, 200* but it usually runs 140*. So I shut it off. It backfired right before I did and had alil smoke coming from the carb. I tried to restart it after it cooled down and it ran alil rough. So I think the weights in the distributor either broke or are not working correctly. I still cant see the mark on the balancer with the light. Gonna try a new distributor tomorrow and re time and see if that fixes it. The one on the motor now is 22 yrs old so it might have let go.
