Dude I feel your pain. I too am from Rochester and two weeks ago had the same exact problem. I wound up going to Big Lake and much to my surprise they couldn’t get it going either. So after about a half hour of good attempts they warrantied the power head and gave me a brand new one of off the shelf. The best they could figure was it was a compression problem. Trust me you should take the time to run up there it’s about a two hour drive from Roch and well worth the time, they will make it right free of charge and when you leave it will be working. Nothing against your local mechanic if he can’t get it going your still gonna have to pay him. Any questions drop me a line I’ll check back later on this post.
