Have a Series 200 motor, tested Ok 90psi. running ok, no smoke, was a bit rough, put it down to the carb being one i hadnt cleaned out. Pulled the stuff off it, put the primer start gear on it, carb, flywheel etc and it wont start. Backfires through the carb. Was thinking it was rich due to no filter so i put one on, still doing it. Swapped another carb/tank onto it, still doing it. Swapped the coil out, still doing it.


Any ideas???


I was thinking of going back to the old carb (if i can remember which one)
or perhaps the muffler is clagged.


A bit annoyed with it, had to mess about to get a blade disc sorted for it, masport bolt pattern, no discs to suit.

Dont want to spend too much more time messing with it.
