I have an FA100 Saito 4 stroke that I took apart and put new bearings in. I did the cam timing the way everyone on this thread says to do it. Now my question... How do I know beyond any doubt that I have it timed correctly without having to take the engine apart and look? Can the timing be checked with a small degree wheel? There must be a way to check besides just starting it up and seeing if it runs (which it does)?
Also, I can't find a muffler for it anywhere. RC Specialties has them but I'm not going to pay that price. Any suggestions?
