smoken cub
I just got a cub 129 that smokes after it runs for a short while. It smokes so bad it fowls the spark plug in no time. It still has plenty of compression to run but i noticed what looks like oil coming from underneath the head gasket. Thier isnt much blow by coming from the dipstick tube while it runs. I hope its not a hole in the piston. Any guesses on what might have happened to it?
