I notice we are not hearing back from the O.P. anymore.
Hmmm.
Not the long block, means he did something wrong. Didn't want to hear that. Maybe his freind didn't want to tell him, either. We all make mistakes. I hope he comes back, and I hope he gets it fixed. As said, this is a great place to learn. I myself have had the same problem, and it was a poor seal between intake and heads.
