Guys,
The Onan has been running poorly for some time. Last trip out it would quit after an hour or so running and when it was running it was rough. I had some issues with the carb, for example could close of the idle screw and it would still run. So thinking it was sucking in air somewhere else I noticed fuel stains around the intake ports so I replaced the gaskets.
Fast forward to today, I just installed a rebuilt carb from JimK. It started right up and was running very smoothly. Big improvement over the previous carb. However after about 5 minutes or so I could hear popping sounds coming from the muffler and the engine shakes. Sounds like it is mis-firing. I have already replaced the plugs and wires earlier.
I'm thinking it might be the coil. I have checked the resistance per the MM and it is within specs but could be breaking down has it heats up.
We have a camping trip planned Friday and really would like to run the roof air during our 3+ hour drive. Any suggestions would be greatly appreciated!!
