skystreaker1a -> Can't understant Rcexl instructions. (11/4/2012 3:16 PM)

Has anyone installed a Rcexl ignition with automatic advance on any gassers? I recently bought a Rcexl ignition cdi with automatic advance to install on my 3.2 Brison engine. The Brison had cdi with mechanical advance which I did not care for. I though installing the Rcexl unit was gong to be a pretty straight forward installation but after reading the instructions that came with the Rcexl module, I'm at a total loss.
The way I understand the instructions, you set the engine timing 28 degrees before TDC and than slide the hall effect switch over the magnet located in the prop hub and when the plug fires, you fasten the hall effect switch down and your good to go. Correct me if I am wrong, but aren't you going to be starting that engine with the spark set at 28 degrees BTC. I always though when one started a gas engine, the spark should be set near TDC or a few degrees ATC to make starting easier with no kick back. Now if this engine starts 28 degrees BTC and you rev the engine up to full throttle and the Rcexl cdi also automatically advances the spark, the way I understand things to work, you’re going to have a plug firing at 56 degrees BTC at full throttle. With an engine running at those specs, its going to run hot and not gain full speed. I can understand setting the timing 28 degrees BTC if the Rcexl didn't have automatic advance, but with automatic advance, I can’t see how this setup can work.
Thanks for any feed back.
