Well trust me I have seen bad stuff from all of the shops listed here. Don't feel that ANYONE is immune believe me. Having been in and around the business for a long time you are not gonna find anyone that will pay for someone else to "repair" the motor and likely will not find many that would be willing to refund the money either. Most people and courts would see the offer being made by the builder and would leave the ball in your court. Don't get me wrong I understand your frustration and frankly can see you did not have a ton of experience at this kind of thing. As pointed out $21Kis dirt cheap for something like that. I usually have in excess of that in parts for something that will make 4 digit power. Juts saying not trying to bash at all

BTW and way off topic but been in North Carolina this week and seems like a nice state to be from. Been downing Cheerwine as fast as I can find it
