Wanted to confirm my timing while I was checking my valve clearances but can't see any casted in timing marks. Not sure who makes this engine but 124cc is casted into it as the displacement. chain looked good and the mark on the magneto lines up to a dot on the case but that dot is not casted in, it is just a spot with no paint !.
Engine side view:
timing gear - you can see the dot in the gear, but there is nothing on the case to line it up too !
Magneto - you can see the "dot" in this photo:
It's running very badly right now so I'm checking everything step by step. Next I am going to seal the manifold better as I think it might be leaking. We put a larger Carb and exhaust on it and working out the bugs now.
