Re: Need guidance with first build!
the head and jug come off real easy if you believe it is frozen. just 4 nuts on the head. and make sure when you put it back on that you piston rings are lined back up with the slots on the rings and the pins in the piston groove. and while you have it off you might as well take some 400 grit sand paper and smooth the edges of all the ports so you dont have to worry about snagging a ring on the poor casting of these engines. just make sure you wipe it out real good before putting it back on. Also believe 14mm if I remember right is the size of the head nuts. the size of socket needed for the gear is 19mm and be sure to turn clockwise and feed chain from the bottom.
