Still not sure yet.. I have the tube to do the brake lever, but now thinking of adding a motorcycle clutch lever and running the cable to the carb.
Or split the seat and make a center console and mount a lawnmower throttle and yes ad a spring to it.
Oh and I changed the fluids in the trans and axle and now the govener works alot better.
Both trans and axle was full but it was dark and thin, trans had a bit of milky at first also.
Now both are full of heavy gear oil.
Pain in the a$$ to get to the plugs and refill it.
