Does anyone have first hand knowledge on the "difference" between the 3W-75i/rear carb and the 3W-75iUS/side carb?? It looks like performance should be the same? Rear carb is heavier by a little. Rear carb looks like it would be harder to mount? and the side carb would need a wider Cowl?

I guess I was wondering about starting, running, fine tuning, etc. Really any difference?


thanks, Ward
