I have a mates daughters here at the moment, it is a Series 450 Briggs on a Sprinter base. It had bits missing from it, it came from her father in law, so I'm guessing he had had a fiddle with it. It had no spark so I replaced the coil and got it up and running fine. Yesterday I started it again to show my mate and it is now hunting on the governor, no probs I thought, just swap a known good carby/tank onto it and all will be good. Not to be, still hunting exactly the same as the original carby. Any thoughts?
