TDC


30 BTDC

I noted that some of you were interested in the timing setting on your gas engine, here is how I set the C&H timing on Saitos, the same can be used to check on your gas engines. I down loaded a degree wheel and glued it to .125" plywood, then cut it out. I drilled a hole through a glow plug so I can hold the engine, (a Saito 150 in this case) at TDC. A piece of control rod stuck between the two center cooling fins serves as a pointer. 30 degrees BTDC is the recommendation for glow fuel, yours would be 28 degrees for gasoline. In case you're interested a C&H unit with Syncho-Spark works perfectly on my FG 11. If I didn't splain it well enough, ffire some questions..
