One revolution, or two?

it depends where they get the signal to fire the coil.... the 400ex motor is triggered off the flywheel, so it fires the coil every revolution (it can't tell if the motor is on the compression or exhaust stroke).
Some 4 strokes get the trigger off the camshaft so they fire the coil every other revolution.
Make sense?

I picked my tiny tach at a Briggs and Stratton (my job) repair shop as we sell them for generators and adjusting governors on lawn tractors. I paid $30 for it. Dennis Kirk also has them but any Briggs dealer can order one I would also pick up a gasohol tester Briggs part Number 100023 as it is only $5 and can detect any alcohol in fuel so you dont run nasty gas.
