Thanks for this I will find the model numbers and mention the decompressor issue
                             Regards Ratt

Asking for a friend who often repairs G/ machinery.
              What is the air gap between the coil / sensor and the tigger / magneto rotor ?
               Two items that have run recently seem suddenly to have high compression, can't be coked up, correct length plug timing right, anyone any ideas, has Simone else experienced this?
       Thanks regards ratt
