My Onan has been very good. After decarbonizing the heads, setting the spark plug gaps correctly, installing Lawrence Gaskins Pertronix upgrade, and setting the timing to a conservative 26 degrees BTDC it has run flawlessly.

I did have a vapor lock problem after mistakenly buying some E-10 fuel and running in 105 degree heat with the AC on. After I returned home I covered the fuel pump and fuel line going to the pump with some foam backed aluminum tape for insulation. I only covered the line inside the cabinet. I have never had another problem with vapor lock. This really was not an Onan problem. It was a 10% craponol diluted fuel problem.

I also did replace the 40 year old motor mounts and the starter bracket with a Ragusa Steel one.

The best upgrade was the Pertronix ignition which Gary Bovee now sells as a kit.
