I replace the engine on a used Sears 42", 6 speed riding mower. My problem is that when I engage the blades the engine stalls. The belt, 1/2" wide seems to be in a bind in the engine pulley groove. It will turn the blades if I manually turn the engine in the reverse direction, but not going in the forward direction.
All of the mower deck pulleys, etc. are turning freely.
The drive pulley is the one that came with the mower on the old engine.
At 1/2" is the belt maybe too narrow? Only thing I can think of.

I think you are right. I have had that happen before and it will bind up.
