Hey all, tried the 4 stroke on 50/50 gas/glow really runs well with that ratio. Concerning glow motors with bushing. I just converted a ST-3000 to gas with EI. I have been running 25:1 mix with Klotz. It has several hrs. on the stand with no problems. ST oil is 10% (12.8 oz/gal) 25:1 is 5.12 oz/gal. It so far has had no problems. I did open the original 2 oil holes 1 drill size and added a 3rd on the side of the rod that is opposite rotation (leading side). Gas is a lubricating fuel. methanol is a "dry" fuel. maybe the lubricity of gas offsets the reduced oil. I am going to put the 3000 on gas glow, now I have to make a glow plug adapter since I drilled the head for a 10mm spark plug. Jokes on me!
