I have a 47 B that is according to the book 180 degrees out of time. I got the fire mark in the center of the hole on the side of the torque tube then set the rotor to the timing stub in the cap. I could not find any marks on either the fiber or the steel gears in the mag to use to time with.It would not start just backfired through the carb.When I moved the plug wires from #1 at 10 o'clock to #1 at 5 o'clock it starts and runs like it is a degree or two out of time.When I give it some gas the higher the rpms the more out of time it seems.does anybody have any idea what to try next Thanks alot and Happy Easter.

Thanks alot guys. I think Steve might be right and I timed it to the exhaust stroke. I'll know tomorrow about that.The pictures were a big help to my fiber gear looks nothing like that but I had the bevel on the steel gear right. Thanks again. Mike

thisis a 4 cycle motor. you are coming up on the exhaust stroke, not the compreeesion stroke. normally you put you thumb over the fron spark hole and feel the air compression for the right stroke. this is what you call 180 degrees off. ---for the timing, slowely crank the motor over to top dead center "top" or "center", not the fire mark. you should hear the mag "click" at this point. that is the correct timing. the "fire" mark is the advance mark after the motor is running.
