In my opinion, here is what a man would do.... he would grow a pair of nuts and call Best Machine directly and ask them what happened....... I dont have a motor built by them, but I can tell you that any reputable engine shop will correct a problem if it is truly theirs.

Posts like this are as bad as someone writing "joshking440 is gay" on the wall of a port-o-jon

Until you have contacted the engine shop, you shouldnt have posted this here
