Good news Bruce I took the carby off cleaned it up, cleaned and re gapped the magneto air gap and cranked it over and got a big fat spark! Thanks for your help!
I think I may just forget about the electric starter...its a bit of a mess anyway..scruffy wires...no key....can i remove the electric starter itself from the side of the engine...or just leave it on there? If I take it off will that let grass etc get in around the flywheel?
Regards
Dave
