Onan P16 on 416-8 Wheel Horse

Recommended Posts

I have a 416-8 Wheel Horse with an Onan Performer 16 engine. I've had it since new, purchased in 1990 +-. It recently back fired and just quit. I am trying to figure out if it is fatally wounded or can be saved. Plan on a compression and leak down test as a first step in my plan to save it. Question is how much compression is needed for the engine to be functional and what would be the guidelines for a leak down test. Thanks ! Great site. John

If you have at least 75 psi, the engine should run.  After that check, I would see if the flywheel key may have sheared when it backfired.

When it backfired and just quit were you mowing? And does it start back up?  The reason I ask as when my ignition module went that's how it acted till I replaced then, Jeff.

Thanks lynnmoor and hillbilly proud - Actually not under load at the time. For some reason (SWAG) I feel the need to check inside the engine. What would be your first step ? Thanks.
