Now if your Glow to Gas conversion is about ready, a simple way to set timing is to just guess where timing ring with magnet is about in the place you want it. Get engine running and warmed up. Set throttle to full RPM. Adjust HI needle valve to fairy smooth 2 cycle-ing. Check RPM with tachometer. Now if you do not think Rpm is at it best....reset timing ring ...advacing it only a tiny bit at a time. When you get full RPM, leave it there if you do not hear detonation. Of coarse you may have to fine tune carb too. Capt,n
