I don't know what rear gears or vehicle weight. I was only involved in building the TH350, supplying some of the engine parts, and helping with carb tuning, plus supplying rebuild and tuning parts.
It's also running in the heat and on the gas carb. The E-85 carb runs quicker and will be back in place in a few days......
