Working through some of the problems and looking to improve the control of the ignition in the Merlin DOHC 8V I'm looking at the feasibility of a flywheel triggered ignition sensor mounted somewhere in the crankcase. This was prompted by Steve Maney quoting that having the ignition trigger on the crankshaft gave a couple of horsepower improvement over the normal cam mounted trigger. Easy to do if your using a belt drive without the primary drive case ( i-e racing etc) indeed Steve supplied components to do just that, mounting the trigger unit behind the engine pulley. Steve's crankcases have the timing marks already engraved on the crankcase as well. I'm planning for an electric start and enclosed primary drive so don't have the space between engine sprocket and crankcase/primary case. Any ideas anyone?
