I spoke with a guy from a fuel injector company that flow tests and cleans fuel injectors. He has a friend that rebuilds and repairs small engines in the Northeast. All the lawn mowers and snow plows that sit during the off season he gets to rebuild the carburetor's on. He does not even look anymore for a cause, he just takes the carbs off and start to clean this white gunk out that sticks to everything. Puts the carb back on and they start right up. He basically stated the same thing that that Rich Thomas said.
That is why I wanted to run the old ethanol out and refill with regular gas if it was going to sit. I am fighting a rich fuel problem now and I hope to get it resolved, so I can go onto to finishing the refurbishing of my chinook. The rich problem I am having may not be a result of ethanol. I just wanted the best fuel in it, if I let it sit for a couple of months. I was also told if you drive the RV on a regular basis you won't have a problem with ethanol.
I had no idea of the problems with ethanol until I spoke with the fuel injector company.
I wanted to see other people's views on the subject.
