[Kartbuilding] Houston, we have a problem

[Stephen Burke]

Hi Ami,

Thanks for the photo. So even if there is no tension on the belt, the 
pulleys still turn?

I don't like using the round belt myself. I've seen the round belts before 
and have seen them used as temporary fixes for fan belts in cars. They are 
adjustable and can be cut to size. I don't know if your round belt is like 
that or not.

I much prefer "v" belts. As you increase the tension they wedge into the 
pulleys and provide good grip. Also, when they are not tensioned and 
loose, they shouldn't grip the pulleys. Unless its a brand new v-belt.

It could be the same with your round belt. It could be very "grippy" 
because it it new. Maybe after some use it will be OK.
If you had a "handbrake" then the kart / vehicle should not move forward 
when starting the engine.

Let us know how it goes.

Best of luck,
-steve
