Hi,

What if you had some small engines you suspected you "ethonolaled" in the fall and havent run in a while.   You did the ScottAR water to gas test and found them to be excessive water?  Would a simple drain and replace before running be a sufficient fix, or should you pull a valve cover and drizzle some more oil on the valve stems or something???

Drain tank, change fuel filter, and maybe clean the carb out. 
Oil change wouldn't hurt anything either... 

If somthing don't sound right on startup, start inspecting...

A little off topic but close.I've got four older deere 2cyl tractors that used to start first compression but with the newer gas their hard starting and once the plugs get wet game over.Seems theirs no light end to the gas now.Have any of you guys noticed this with your older rolling stock?Frank C.

Well there has been to major fuel changes since that motor was built. They liked the old leaded gas, You take away the lead and add a water absorbing additive to the fuel and they do not like to run the same. Try to find non ethanol supper and that should help. Off road gas for off road vehicles.

Frank, I would think it is a fuel volitility issue.  Winter fuel (highter volatility) on a warm day any better?

Dr B
Check that the fuel shut-off is working...sounds like it is not.

Should have it if it is fuel injection.

There is a fuel shutoff solenoid built into the carb. Shuts off the main jet when you turn off the ignition. It's probably stuck open with gum left from evaporated fuel or corroded from water in the ethanol.  Look on the side of the carburator.If you see a small wire attached, pull it off with the engine running. The engine should die immediately, if it doesn't the shutoff valve is stuck....

Cappy, even in warmer weather the tractors don't start like they used to.They put something in the fuel so it won;t evaporate into the atmosphere as easily.I'll try to find high test without alky and try that .DanG old tractors I don't want to spoil them,they'll want the good stuff all the time.Frank C.

The reason that some (not all) high test gas does not have ethanol in it is that when some states were considering mandating ethanol, various groups lobbied to make sure non-ethanol gas was still available. [Some piston aircraft can run on auto gas, but ethanol is definitely prohibited. It's a problem for marine use (ethanol eats some fiberglass fuel tanks, and many boat engines sit longer than cars between use, giving the ethanol more time to suck moisture out of the air). Two cycle engines have a tougher time with ethanol.] Premium gas was picked because it's already something of a "specialty gas" - and because few people run premium in their cars, so making it free stil tended to maximize the use of ethanol-laced gas.

Don't be fooled into thinking that all premium gas is ethanol-free. It's a function of what that state's regs say. And even in some states that allow ethanol free premium gas, they don't necessarily prohibit ethanol in premium gas.

I'm fortunate in my area - even though most gas stations have around 10% ethanol in everything they sell, there are one or two who get their gas from Canada without any ethanol, and a small airport that sells ethanol-free premium auto gas (they don't stock aviation gas). I make a point to buy all my chainsaw gas from one of these sources.

I've been running high octane in all of my gas equipment. I've been told that there is no ethanol in the high grades, but cannot verify. Mid grade is a blend of high octane and regular, so I avoid it also.

Don't know who told you that but all auto fuel sold in mASSachusetts is "oxygenated", a.k.a. "corn fed" up to 10% ethanol.

Ethanol will react with aluminum or magnesium (more so) so it will also eat up uncoated fuel tanks and carb parts.
