Spotted this rather nice looking unit for sale with the usual blurb about it no longer starting etc, could see that the the top cover had been removed and starter cord hanging out etc. Contacted the seller, yes it's all complete, my son tried to fix bla, bla. The picture was one side of the mower only. I get there and this is what was done ! strangest thing is the mower is in excellent condition deck wise, wheels, chrome work and as I suspected is a self propelled model. Anyway, i had parts to convert back to what it should be but I can't get a spark ! done all the usual checks and tried coils I know work but no spark. It's a Quantum series Briggs. Any help appreciated as always.
