How would I know VA or UA ? I did a compression test. 120 average and a leakdown test showed valves good. Or at least sealing. And showed head gasket good. Huge build up of carbon around valves from a bad carb. My model does have a mechanical fuel pump. And no writing on timing cover. Timing gears are set pointing towards together / center of gear set. I am thinking maybe I dont have a bad engine. It ran today @.015 valve lash. Carb is crap. Tried 3x to rebuild or clean it. No success. Distributer/points are set @ 30 I think. It runs, smokes fuel, crackles and dies. Will not accelerate with carb at all. When warm it doesnt want to start. I do need a side draft carb. or kit if you know of any?
Thanks , Jon
