To check the timing, it is easiest to due it with the pull start cover off. There is also a timing check plug over on the top surface of the case by the pull start. (Larger slotted screw/plug). Remove that plug and looking down you should be able to see your rotor. Loosen the cam chain tensoner. Put a 17mm wrench on the pull start basket bolt so you can turn the engine over, removing the spark plug will help too. Remove the cam chain cover from the engine head. There is a pointer on the engine head by the (top of the cam sprocket) , with the wrench, turn the engine over so that the line that is cast into the sprocket aligns with the pointer. Look into the timing check plug. Hopefully you will see a line there with a "T" by it. If you don't turn the engine so the cam spins 360 and check again. The pointer and sprocket mark need to be aligned with the "T" mark line in the timing plug. If these don't line up you will need to remove the bolt holding on the sprocket and move the sprocket X number of teeth forward or back on the chain until things line up. Tighen the cam chain tensoner, spin the engine over 360 and recheck the marks. Hopefully you will see the two marks that need to align at the sprocket and the timing mark on the rotor when you get into it. It isn't that difficult to do, just use a flashlight so you can see down at the rotor easier.
Anyone know of a new project machine for me around Wisconsin?
