Thanks guys
got some time to have a good look today fired it up and put the revs up high no drive or cutter spinning, then noticed smoke coming from the centrifugal clutch turned it of with difficulty lol! will have to ajust the throttle I think, unfastened the motor and moved it to one side so I could see the clutch looks like it works similar to drum brakes and the pads look worn and were very shiny almost like they had something on them like wax or something tried to scrape it of but it didn't want to come of. Can you get new pads if so how are they fitted if not can mine be adjusted.
Thank you again
