b40rt Posted May 20, 2010 Report Share Posted May 20, 2010 I would drain carb, and change the plug. After that try another coil if you can borrow one. Quote Link to comment Share on other sites More sharing options...

b40rt Posted May 20, 2010 Report Share Posted May 20, 2010 (edited) worth checking that the pivot points for the points and advance retard are greased. Edited May 20, 2010 by B40RT Quote Link to comment Share on other sites More sharing options...
