Do your local farmers run all the equipment a lap around the field once a month in Winter?
Just let it be.

Isn't generator exercising recommended for the generator itself not the engine?

I'm not sure why this would be important for a brushless generator but...?

Anyways I do know people who start a $35,000.00 diesel engine and cold idle it to "charge up the batteries..."

Anyways - one thing that was sure with propane fuelled vehicles back in the day ... anything that malfunctioned under the hood was attributed to "that propane you got on there..."

Like every diesel hiccup is "an injector..."

The purpose of staring combustion engine during storage is to evaporate water that might condensate in crankcase.
That doesn't apply to dry climates where I live and it takes warming up the engine to full operating temperatures to evaporate the water.
Short idling without load can actually do more harm than good.
Electric motors/generators can sit for years and will run just fine.
I have whole fleet of small tools with combustion engines. Some of them are over 20 years old and can sit for 2-3 years without starting.
All I do is run carburetor dry before storage and when gas is over 2 years old, I drain it and put fresh one.
Honda engines with fresh gas will take 1 or 2 pulls to run again.
Other engines take several pulls.
Only on 11 HP Honda engine I had to replace carburetor orings at 20 years mark.

We are not talking about diesel farm equipment here, instead PROPANE RV generators. I don't see a comparison.

If you think propane engine is not prone to water condensation, think again.

Slymer - Compression, fuel & air in roughly the correct ratio, spark, and sufficient cranking speed and the engine will start.

Propane mixture in cylinder has a higher resistance to ignition than liquid droplet fuel (gasoline) One thing to check is the plug gap is in spec for propane. This is more of an issue under heavy load.

I still suspect fuel starvation.... if you give the engine a little whiff of starting fluid does it fire and try to run?

I have tried quick start fluid, with no luck, but this is not an engine. It is a built-in propane generator. Definitely getting spark and all other appliances are getting propane but it appears the generator is not. I have managed to get a couple of hoses off & blow them out. Still no luck. Just cranks over & over.
Got it running about a month ago, finally,.....but now again no luck.

Ours when setting the connections to the fuel solenoid lose connection (corrosion).
If I don't hear a loud click (solenoid opening) I stop & go clean the terminals to regain contact.

Oops my bad I thought it was an engine driven generator like my Onan.

If there is no fuel a safety shut off valve is not energizing to open as mentioned, or the supply line or filter could be plugged.
