sandman Posted December 12, 2016 Share Posted December 12, 2016 Can anyone help, got this Pubic black devil light that refuses to tick over at less than 3200 rpm it is clutched so is that normal ? top rpm is over 8000 but I put that down to under pitched prop, also it kicks back like a B******* on the flash starter. plug gap is spot on to within 0.05mm the air gap on the wheel is cock on , is it carb setup or my pull technique? or something else. any help will be appreciated Quote Link to comment Share on other sites More sharing options...
