RE: starting with the choke on?
Just for the hell of it I just tried the "other" starting method, that of choke on but without the ignition on, and was rewarded for my efforts by flooding the engine. Of course as several of us have found out, removing the cap on a CM-6 plug can at times be challenging and this time was no different. Pulling the plug I found it filled to the brim with gas.
Wiping it dry and replacing it after a few smart spins of the prop had cleared the cylinder, and using the tried and proven start technique, I had the engine going in no time. So much for my trying to re-invent that wheel.
