“I’m a big Guy.300 in full dress. Does that change your view on the engine choice or axle size?”
I’m not sure a Chonda OR an LO206 would be good for you based on your body weight. In my opinion, a two stroke, like the PRD Fireball, might be better for you. I think you would be quickly frustrated with the lower performance of those 4 cycle engines, even when you are just running laps for fun.
