Propane gennie maintenance in cold winter

You don't need to do anything to the propane generator during the winter or any other time it sits for long periods.

Fire and fuel
After the cold is past make sure you have a spark at the plug then light your propane stove to make sure your regulator is working and lastly with strong battery try to start the genny.

I’m not sure why it would take you hours and hours to get your generator back going or why you need to run your generator during the Winter an hour each month. What was wrong, or what did you do to fix it?

You should be able to prime the generator and as long the battery is good, you shouldn’t have an issue getting it back running. One other hint to to ensure the propane lines are full by running other items like the stove.

I’ve had the case that the propane fuel had either water or too much additive in it. That caused my generator to sputter.

Strictly propane. It was stock on the 2013 AF 811's. Cummins/Onan.

A propane gen should not gum up like a gas genny. Do you also run it on gas? If so run the gas out and drain the carb then run some seafoam in it. Put a small amount of light oil in the cylinder. And turn the engine over by slowly pulling crank.
