RE: Question about gas to oil mixture........
There is about a nickles worth of difference between tuning a gasser and a glow, maybe only two cents if that. A high end and a low end. Set the high end first then the low. If it idles then let it do so for 20 or 30 seconds, crack the throttle open, if it dies right now then your low end is too lean, if it burbbles then the low end is too fat. Nothing to it if you don't over think it. When it goes from low to high smoothly then you adjust the high end one more time, bring it to max. RPM then back off a few hundred so it doesn't run lean in the air. Like any engine you need to know the working RPM range. Prop the engine so it never goes over the top of the engines RPM range or you will get a lean run.
