    • Did you replace the belt?
    • If you did are you sure you have the right belt?
    • The right pulley on the new engine.
    • The right engine?
    Would need MTD Build numbers, and B&S engine numbers from both engines for cross reference.

    The mtd model is 13ac762f729
    The old engine number was 21b807
    The newq engine is 21b977
    I used the same pulley on the engine as this was also a 1" pulley
    Thank You for answering so quickly

    Your welcome,

    What I found so far is the 21b807 crosses to a 21b907 not the 21b977. There are some differences, mainly horsepower.

    You sure you routed the belt correctly, is this it?
