ONAN Marquis Gold 7000 Gas

The spark timing is fixed. The flywheel is keyed to the crank and has magnet inserts. I set the coil air gap with feeler gauges. They are magneto type coils and the small white wire is to ground them to stop the spark.

I have a sequence for doing the belt and tensioner and it’s pretty easy once you do as many as I have.

I made up some various tools to do these machines.

Flywheel puller plate , chain rig to lift upper section off base.

I pull engines off the base and split the case to replace the base gasket when one fails. Cleaning that mess under the base takes some time and a lot of chemicals. WD-40 works very well and some other solvents and eventually Brakecleen....
