Jenny/Emglo compressor opinions

Funny, I've had to replace several old float bowl gaskets in the last few years. I wonder if it's something about the gas.

I don't know, Jim. I have an electic Emglo (two sausage-tank variety) that I've had for over 15 years. It gets pretty light duty, but still works for its living. Nothin' ever replaced except the intake filter and oil/filter.

How is this related to carburetors?

That, or letting the gaskets dry out between uses/old drying gas varnishing up...

Which is the problem, storing dry or letting the gas deteriorate?

Or both?

The bowl gaskets crumbled when I removed the bowl to clean and dry it before putting the engine away.

I can honestly say that I have never had a problem with gas going bad, in CA, AZ, or OR. I usually start things up every year, so fresh gas is going in once annually, and I store it outside in a semi-open shed. It's all ethanol-douched now, too. (hate the stuff)

Things I've bought from garage sales usually had problems from being stored for ten years or so with gas (or gas/oil blend) in them. But because I always rebuilt the carbs on auto engines which had been sitting more than a year, I never had too many problems.

I think I've seen more problems on yard implements from being stored too long with gas/oil in them. I've seen gasket leaks on dry-stored motors, but they usually -run- on the first fillup without problems.

Yeah, probably C- both of the above.

I sure like the nitrile o-ring bowl gaskets on some MC carbs.

Ethanol eats neoprene - I won't use any gas containing ethanol in anything but my car and that is on lease.

The problems I've noticed are oxidation (turning rancid) which I can smell and gelling which a filter screen funnel removes, or I blow out the infected carb with air. Turning yellower is a common indication of deterioration in a wide range of organic compounds.

I believe without proof that it keeps well in nearly full sealed containers that exclude oxygen and moisture, which means 1 and 2.5 gallon cans for small engine gas so they don't stay partly empty for long, but I don't use enough to really test my theory.

When I need one carb part I buy two, and label the spare.

Good idea. I wish I'd had a spare Ford carb kit in the Ranch Wagon after rebuilding one on the side of the road in the Mojave Desert once.

I left my old stash of intermixed hardware (nuts, screws, bolts, washers, rusty nails) in the garage at the old house, on purpose, and I seldom miss it.

Now, when I need something like a dozen nuts, I'll buy the box of 100. It's usually cheaper and it's a proven size that I needed. All new, all sorted, all usable, no time delays to fish out of a dirty tub.

Zoro Tools on eBay is a good source of cheap bulk fasteners. So is Sasco Fasteners in Medford, OR, 27 miles away. A local Ace hdw store wanted $32 for 26 M5x16 SHCS, Sasco gave me a box of 100 for $5.13.

The Octane boosting volatile gasses leach out of the gas and it 'goes flat'. Looses octane. There are gas additives that help boost these.

With the advent of the OH crap in the gasoline, water is a key element that gets into the gas. The Alcohol is hygroscopic and absorbs moisture and waters down the gas.

The Rubber hoses are melted in some of the additives. Many a engine fire occurred as they started the experiments.

New cars have Neoprene which is ok. I've never heard of it dissolving.

Like I said, I can't remember ever having a problem with that here on the Left Coast in the past 40 years, and I keep some cans of gas for 2 years (gas/oil for the weedeater).
