well to be perfectly honest, the problem was that the distribution chain had one of its guide break, so that timing of the engine got messed up, that made the cylinders run off beat resulting in the valves getting all twisted and stuff, so the part that houses the valves needed to be rectified, plus it's currently running on a different carb than the original one, it's bigger but it still doesn't go that well, I was also curios as to if this engine type accepts a snorkel or am I just dreamin here
