torque converter
 

i like to get more power out of mytorque converter,i have a 10hp robin engine.what can i do to fix this

I'm assuming you have a Comet style CVT. Not much you can do- change to a stiffer spring in driven for faster upshifts/more torque quicker.To get more top speed you can change the driven to a smaller diameter one.Bigger sprocket@ axle or smaller @ driven for more torque- visa-versa for top end speed.Clutch unit has no mod's that I'm aware of.
