The Westinghouse is also one of the only generators I know that has an auto choke. We never plan to run this on gasoline, just propane. Champion makes a wireless remote starter too, but it does NOT have an auto choke. Unfortunate in my opinion.
Auto choke on a generator from the Mfgr. Cool++. I didn't see that in the link. Please keep us informed esp in the cold weather. How cold does it get there over night and through the day?
The Kubota propane engine on the system I watch is outfitted with an engine control module that watches oil pressure, coolant temp, over crank, etc. and has an auto choke function that pops the choke a second or two after cranking starts if it doesn't fire right away. Didn't come from Kubota, the gen shop that builds them added it as part of the whole electronics / governor package.

I had to add a battery minder last year, as the owner didn't run the gen set all summer because the panels provided all the energy needed. They went to fire it off, and got that nice 'machine gun' staccato brrraaap of the starter solenoid pulling in and dropping out over and over again..

I may date myself but going back to a small block v8 with the heat riser across the intake manifold with the link to the carburetor for the "automatic" choke - it mostly worked when it worked. I really like gasoline and diesel fuel injection these days. They really work when they work.

About 30 during the day, and sometimes the nights get down to 5.
