Yeah I put fuel shutoffs on my snowmobiles now. Those are 2 stroke engines so I 
don't run them dry but I burn them down some. If I'm feeling particularly 
enthusiastic I'll dump the carb bowls but combined with a good dose of seafoam 
gas additive I haven't had any trouble for a few years.

All true... however, propane engines do require more propane to make the same 
energy as a gas engine in the same application.. propane simply has less 
carbons to burn in the chain.. 

If you are using a gas fired generator.. do two things on shutdown.. 
1. Shut the fuel off while the generator is running.. If your generator does 
not have a fuel shut off valve.. get one.

2. Run the carb dry of fuel, until the engine shuts it's self off from fuel 
starvation.

By doing this.. the amount of damage done to the carb from dried out fuel 
varnish is minimized. Most restart issues will be reduced if not eliminated.

It requires only a small effort on shutdown.. which will save, often, huge 
efforts on startup.. which usually happen during an emergency of some sort.. 

The other survival suggestion I would make is to add a "Y" connection to the 
fuel line from the tank and add second fuel shutoff valve, with hose [a large 
golf tee in the open end, to stop critters from making nests in the hose. 

On shutdown, after running the carb empty.. put the hose from the "Y" 
connection into a suitable gasoline storage container, and drain the generator 
tank. dry..  Again.. no varnish or stale fuel on startup... If the stored fuel 
is over 90 days old.. use it in something.. get fresh...

I've read that gasoline engines operated on propane are much cleaner, almost 
never experience carb trouble and can go longer between oil changes because of 
it.

Most gasoline engines - and therefore generators - can be
converted to run on propane. A bit less power, but no issues
with long term fuel storage!
