Looks like the chain could use some lubrication and something in the front end is causing uneven tire wear. Looks like a beast though!

Could you take more pictures of the jackshaft setup? I cant imagine what's going on in my head. Why is that chain going around that sprocket in front of the engine? If the jackshaft is in the back, it seems like the chain would go from the jackshaft to the rear axle, and not forward unless that is some sort of tensioner or something. Looks like a **** ton of power, bro!

The reason its uneven is because the steering wheel its self is put on wrong .its 15 on jack shaft goes down to a 23 tooth sprocket .then comes out on the other side and goes 10 going to 36 tooth tires are 24x11 -10 id say the chain size is like 520

Assuming I got your numbers right into my Excel spreadsheet calculator (I like doing things myself ;), I come up with 5.52:1. With 24" diameter tires at 3600RPM, you should be going over 46MPH. That's not factoring in the torque converter ratio which should add even more speed as the RPM goes up.

With 31HP and the torque converter, you can probably climb trees with it. Will it pull the front wheels off the ground on take off?

Dont know yet it needs a fuel pump right now its using one thats a pulse pump that is activated by something in the motor that pushes the button on the bottom of the pump But its not working .The pump needs to be rebuilt so i went out and bought a 6 psi low pressure electronic universal fuel pump. It's hard to get the last numbers for the tooth count when there behind a plate so i took a crack at a guessing the tooth count i went out there pulled the plate off and counted 15 to 23 on the chain coming off the jackshaft going down (Right side) then on the left side it comes out and goes from 10 to 30 .
