power problems

[buzzwest]

I just finished my 8hp kart and i was having trouble getting it to run the best.
It works fine on a road without and hills but it is having trouble in grass. If it is moving, I can keep it moving in grass, but if I stop it won't start moving again.
help needed

there is a 10 tooth centrifical clutch and a 54 tooth sprocket on the axle. I think this gearing is off so any help on what to do would be great.

how big are your wheels?

it's not spinning out or anything

measure the tires. Then use speed caluclater to see top speed if its over 35 its going to have low low power.

This is one of the reason's many off-road carts use a torque converter. Trying to get a cart moving with low HP and high drag (grass/dirt/sand), requires a lower gear to provide more torque to the wheels.
