What's the correct setting for the TTO tach hour meter in terms of the PPR ( pulse per crankshaft revolution) for the 150cc gy6 engine?

I presume by TTO you mean 'Total Time Operated(ing)', like an 'hours' meter found on an aircraft, or heavy equipment (where there's no way to accurately measure use through distance). If I'm not mistaken those are called ' Hobbs Meters' (don't ask me why) and they are generally run off a 12v electric current. When the ignition is on or, (generally in the case of diesel) the engine is running and turning an alternator/dynamo, the meter runs, marking elapsed time. |

You set it for firing once per revolution. Our plugs fire on every stroke on a gy6.
@pssthpok: The Trail Tech TTO is a combo tachometer and hour meter. The tach works off pulses from a wire wrapped around the spark plug wire. The Total Hour Meter works based on a simple digital delay, if the circuit doesn't receive a pulse within a certain number of milliseconds, the engine is not running.

So it's set at the default of 1 PPR. |
