Very few vehicles are e85 compatible, and only fuel injected engines can run e85 AND lesser ethanol blends. Carbureted engines need to be jetted specifically for e85.Agree on the whole Ethanol deal. What I can't figure out, is if the entire automotive industry can adapt to Ethanol based fuel, (up to and including E-85), why can't the small engine industry? It's not like this stuff is going away any time soon..... If it ever does. Cars and trucks can handle 10% Ethanol just fine. And have for the last 30+ years.
If anything, they are now pushing for upping the Ethanol content from 10% to 15%. So this will, in all likelihood, get worse, not better. Yet here we are, with just about EVERY manufacturer of small gas engines still producing engines with outdated fuel systems, that cannot handle Ethanol based fuels. And as far as I know, no one is even attempting to solve this problem with fuel systems that can handle Ethanol. Thus far none will without going to he!!, and causing a multitude of problems in a very short period of time.... Like the one's you've outlined.
Even the motorcycle industry, the outboard motor industry, along with the entire personal watercraft industry all can handle Ethanol based fuels just fine. You would think Honda, of all people would be the first to get on the ball with this. They manufacture motorcycles, outboards, as well as an entire auto industry, that all run on Ethanol based fuels...... But not their generators and other small power equipment. This can't be a Moon shot to make happen. And with what they're charging, it should have happened decades ago.
Small engines run ethanol blended fuel fine, the issue is letting the fuel age in the carb. Ethanol blended fuels are harder on small engines because carburetors are small. Their passages and jets are very small compared to larger engines. Small passages gum up quicker and easier.
A Priming system would be cool, but I feel it’s hardly a deal breaker.I agree. For the HUGE PREMIUM Honda charges for any, and all of their generators, they should come with a priming system, AND Ethanol based fuel compatibility.
As for the Yamaha suggestion, the less capable ef2000is is gravity fed, and the almost as capable ef2200 has a fuel pump as well. Same boat when running carb dry.
