Engine help please!!!
Took my thundercat out a few weeks ago, started fine & ran perfectly.....until i took it up to full throttle. thats when it wouldnt gain revs & ran really lumpy! Its fine on idle upto 3/4 throttle then it goes lumpy!
i havent had the time to have a proper look at it yet but wondered if anybody on here had any ideas? Its a tohatsu 50 if that helps?
before i took it out i changed the kill switch unit & spark plugs. i checked the old set of plugs & still had the same problem so cant be them & dont think it could be caused by the kill switch unit at all?? but i dont know...im not amazing with engines, just know the basics!
