Hi James,

I got 20mph with a 3.5hp briggs and stratton engine. I used the 
belt-tensioner clutch ( as on: 
) and while the take-off was slow (working the belt tensioner clutch), as 
the engine struggled, once I got going, it got to 20mph no problem.

As a result, I don't think it will be the size of the engine that will be 
the problem. It will be making a light kart. If you can get a better 
steering setup, that would be brilliant. As you said at fast speeds 
steering with your feet is not ideal.

Best of luck,
