Gentlemen, I have been reading the past five pages of information on the fuel conversions.
I'm working with a late edition of the MORTON M-5. The engine will run reasonable well on glo fuel, but wont produce much power. The original carb design is almost impossible to adjust while the engine is running. My solution has been to install arather long manifold, and attach an O.S. carb. I've been told to use a carb scaled to one cylinder, since only one cyl draws at a time. This has proven to be not quite true. Regardless, I'd hoped to realize a few more R's from gaoline. The original design (circa 1944) recommended 4:1 gas/oil. This is a real mess. Spark ignition is out because of the RF issues. Shielding is really clumsy on an engine this small. I do have a McDaniel glo driver. When I start on a gas/oil fuel I have to keep choking the engine to pull in enough fuel. The engine sounds a lot stronger with gas. I built the engine with 8:1 compression pistons. That's what I'm working with right now. I just finished a set of 9:1 pistons, and am waiting for a set of rings. I suppose I could make the rings too, but I'm lazy. I won't make anything I can buy at a reasonable price. Any thoughts on making small engines run on gas would be appreciated. The MORTON has a displacement of .95 cu in. It is 5-3/8" in diameter.
Thanks, Otis
