If he is indeed a professional and a buddy then perhaps start with him..
We can debate for hours the possible causes, but truth is we don't have a clue what's wrong!!
Your buddy should pull the motor, pop the top and give you an answer in about an hour..
If it's on you or something you did, I guess he'll hand you a bill..if it's related to a mistake he's made or a part he supplied and installed I guess it's up to him to decide if he's gonna repair it as a warranty/workmanship repair.
The proof of the issue is in the motor..
No point getting defensive about the 'tone' of someone's post..they are just calling it as they see it and you did ask for their opinion. Sometimes opinions come sounding that way..you may need to thicken up and bit and listen to the message being offered!
