Okay to Run Canned Fuel Through Generator to Clear it for Storage?

[Chips O'Toole]

This is not exactly a machining question, but: can I run a little canned chainsaw fuel through a 4-stroke generator to prepare it for storage?

I'm in Florida, and I don't know if it's the humidity or what, but even with no-ethanol gas, carbs get messed up here when stored. Running them dry doesn't really help.

I learned that old timers used to run pure oil through their carbs to keep chainsaws from gumming up in storage, so it seems to me that if I can do that, I ought to be able to run 50:1 canned fuel through a generator for a minute or so without messing up the plug or anything. The fuel should resist gumming because it's not garbage gas, and the oil ought to be good for the carb's insides.

Well, I feel stupid. Right after posting this, I learned there is such a thing as canned 4-stroke fuel.

OOPS. It has oil in it.

Sthil brand mix has magic juice in it, have had ca gas in a can for 2 years and worked well.

Lot of people swear by Marvel's Mystery Oil . I've used it in tractor motors but not chainsaws . Stihl and Husky 4 stroke is just high octane ethanol free . At 9-10 bucks a gallon ?????? You can buy this off a dock or at any local air park .

StarTron is great , as is Stabile . I've found out that neither lasts over 2 years .

I run some canned 50:1 through my 4 cycle engines before I store them, seems to work fine. I run the old fuel out than add some 50:1 canned fuel and then run that dry.

If burning a little oil won't bother the generator, I'll just run some Husqvarna canned chainsaw fuel through it. I would run oil into the carb after running it dry, but it would be a lot of aggravation.

If you have no-ethanol (rec) fuel that should do the trick. You can use fogging oil, just remove the air filter and spray it into the carb until the engine dies. This is what we did for boats.

I don't know why, but here in Northern Florida, saws run on no-ethanol fuel clog up just fine.
