Runs fine up to 1200 rpm, then heavy vibration. I have another Jackpot and it runs great. Had this problem with my first Jackpot and it turned out to be a collapsed fuel line.
Dealer won't work on it because it has a PCV and they don't have software. Going to take the PCV off and start from scratch. Instincts tell me the fuel system is compromised somewhere. Giuess I'll just start with a new fuel pump and go from there.
