Hi there iv got a scorpa 175 4 stroke nice fun but iv been having problems with it. If I take it all apart down to the carb block the carb and she will start only for a couple of seconds iv had the carb off and cleaned out. Iv even blocked the carb with tape and put a few holes on it and she will burst into life a couple of revs and just dies before she would stay running when j went to give her a wee Rev to hop over a ditch and soon as I was giving it throttle she would want to died. Am fighting with my dad he says it’s fuel and I think it’s a new piston and rings. If anyone can help please either write on here or email me at kevmac1989@gmail.com plz thanks
