Johnson 6HP Dies at WOT

[Pyp]

Thanks to all that helped on previous issue with carb, all sorted now, engine runs nice @ idle and at half throttle, @ WOT bit of back firing and engine starts to die, anybody point us in the right direction??

link n sinc, dirty high speed jet. check and see if flywheel key has sheared. flywheel has to be torqued if it was removed in the past. could cause backfire.

high speed jet, all clean, flywheel key in good nick, but did'nt know about the torque setting for the flywheel bolt, anybody know off top of their heads? could it be anything to do with the 2 adjustable screws on top of carb?? 1 with a spring round it (close to choke) and the other 1 right at the back? Many thanks again Ian
