yes it was a dud coil but with the honda coil on the timing was out with only having one bolt hole lining up was getting spark at wron time and the exhaust manifold was glowing red/yellow when running but on fitting the new coil setting the air gap etc it ran a treat but still had glowing exhaust on the cylinder with new coil fitted so after swapping coils round changing plugs etc worked out that there is only a very very small air gap to circulate air from the flywheel through the head fins and tin cover around the cylinder head/barrell as as i was workg in the dark it was hard to work out that the cylinder that had,nt been working for a whileand its cooling fins blocked thus no airflow on one side of the engine so that cylinder was working but not cooling thus the red/yellow exhaust port i even had the exhaust system off to check valves was ok and not burning fuel in the exhaust instead of the cylinder sorted it in the end though but was a head scratcher and had me baffled for a while we never stop learning do we ?
