    Do not give up on the engine.

    I ran mine through two chains and it was great. While I was feathering the throttle it didn't run well, I ran it wide open and treated it terribly and it ran amazingly.

  • N

    If you can get this to work it is insanely fun

    This was a perfect price to find out the motor industry is not for me! Glad I only made a $150 mistake instead of $15,000 or more! So thank you!
