OK, a couple of updates.
First, I have discovered that one of my cul-de-sac neighbors, actually has a propane tank installed! Interesting! Apparently, it was approved as the house did have 1-2 devices that used gas and not electricity. Most of the houses here are "electric" only. I'll have to look into that with both the county and the HOA's ARC to see if I could do it now. If so, then I may be able to do a 22 KW home generator (probably a Kohler).
Second, I had heard reports that the Westinghouse portable gen sets have a nasty failure point... They run great for a bit, but, after a while, you can't get them to start. Sad to say I have contributed to that statistic.
I took the generator out yesterday to test it and to heat it up so I could change the oil and install my new drain valve in place of the standard plug.
But it just wouldn't start. It does "crank," but doesn't catch. I tried everything. I even pulled the manual "lawn mower" like cord to start it (with the manual choke engaged), and nothing. Well, not totally "nothing." I went back to using the electric starter and, believe it or not, it actually did start.... once.... for about 15-20 seconds. It sputtered and bucked and smoked (out the exhaust), and then it shut down. Could not get it to start at all, after that. I even tried the manual back up cord procedure again, and.... nothing.
In the "troubleshooting" section of the service manual, there's a big section for, "Engine won't start" and for "Engine starts but shuts down." The "Possible causes" include the following:
- Low Oil (it has a sensor for that which shuts the engine down);
- Dirty Air filter;
- Spark Plug faulty or "flooded" engine (i.e. spark plug improperly gaped);
- Fuel filter restricted or fuel pump failure;
- Bad Gas.
We can eliminate the "low oil" because I filled it full just before attempting to start it. It could be any of the others, though. It's certainly not the "battery switch" being turned off (another possible cause) because it wouldn't crank if that was the case. I don't think the engine is "flooded" because I stop attempting to start for about 1/2 hour each time.
If I had to guess, at this point, I'd say it's the "bad gas." The gas in the gen tank is over 1yr old, but it's "non ethanol" gas that has been treated with STA-BIL. Quite puzzling. I couldn't believe it was the other things (filters, spark plug, etc.), as I haven't even put 10 hours on the generator yet. The oil that was in the reserve (before I added more) wasn't even "dirty." It could also be gunk in the carburetor. One of the YouTube suggestions for that is to apply a little "Gummout" or similar cleaner to clean out the carburetor. I can do that easily.
I can get a "maintenance kit" for like $30.00 (includes spark plug, air filter cartridge and fuel filter). That's easy. If it is bad gas, I can pump/siphon it out and replace it with fresh gas. If it is bad gas, though, I face a dilemma. I still have 10 gals of that "non-ethanol" STA-BIL treated gas in my 5 gal containers as well as what's in the gen tank. If that kind of gas can go bad so quickly, what will that mean in re: "preparedness?" Should I even keep any gas on hand if it isn't going to be used for a over 1 year (even if treated with STA-BIL)? Will I be able to fill my containers at the onset of a power hit if I elect not to store a gas reserve? Probably not. I can get rid of the "bad" gas and replace it every time I rent a car, and I can do that on a regular basis, even without a power hit (perhaps every qtr).
Another alternative (and perhaps a way to test to see if it is bad gas), is to (temporarily) switch to Propane and attempt to start it with a propane tank. I can get a 25lb propane tank without much difficulty. But should I empty the gasoline out of the tank first to minimize the risk of explosion? Does the propane option use the same spark plug chamber (perhaps mandating maintenance of it prior ro testing)? I have seen YouTube videos where his gen wouldn't start and it came down to replacing the spark plug. Fired right up after that.
Anyway, just curious as to your thoughts on the likely cause and what I should try first. Replacing the bad gas is a bit of an effort, so if I can do something quicker/easier (spark plug, air fllter, etc.), I'd like to try that first.
Thoughts? Thanks!
