if that were the case, wouldn't you think that all you folks up there in snowmobile & Quad country would have had this problem too?
Just asking...hoping for more insight.
Early December I had trouble starting my Honda Rancher due to fuel starvation. I ended up rebuilding the carburetor that was contaminated with a white pasty crap.
Research revealed the white pasty crap is the aluminum in carburetor corroding to aluminum hydroxide, aluminum's version of rust. If left as is the aluminum parts will die a slow death.
There are two mechanisms that occur with ethanol. Both mechanisms are a result of the ethanol absorbing water. The more ethanol in the fuel, the more water there will be in the fuel, especially after storage. Water causes aluminum parts to corrode. It also causes corrosion particles to clog fuel filters, fuel systems, and damage engine components. Aluminum hydroxide turns to aluminum oxide with heat (think combustion chamber) that is used as an abrasive in sandpaper.
The second mechanism that can occur with the use of ethanol based fuel and aluminum is galvanic corrosion. The corrosion will be worse for aluminum if other metals are present such as copper that is in brass fittings and jets or in the aluminum alloy. Gasoline fuel is not conductive, but ethanol and water will conduct electricity.
The only problem on fuel-injected machines is fuel separation in the tank since no fuel is stored as it is in a carburetor float bowl. To avoid this I now use a fuel stabilizer with gas drier when the machines are put on hiatus for the season.
The drier will bond with water and gather at the bottom of the tank. When you want to ride again you can remove it either by draining whats at the bottom or sucking it out with something like a turkey baster.
Sadly our 250 Reflex will not start and have had trouble starting this past year. I drained the fuel bowl, drained and refilled the tank with treated fuel and will rebuild the carburetor when time allows.
I’m happy to say both Wings and the Bergman start and idle, the Rancher is running like a champ and doing its winter duty.
