RE: Difference between 2- stroke and 4- stroke glow
I disagree Britbrat. I run the same fuel in all my engines, Power Master with 10% nitro and 18% oil. Four strokes run just fine with it. The only four stroke that I know of that prefers higher nitro is the YS.
I'd say hgiles said it pretty well. If you use throttle and like good torque at the lower end of the rpm range, definitely a four stroke.
