My generator has not been started for 2 years. It was properly winterized and fogged before storage. I had to replace my fuel tanks due to ethanol 10% fuel. I have brand new tanks and a-1 rated fuel lines. The generator ran great on non-ethanol fuel before it was stored.
After repeated attempts, the generator would not start. Finally I sprayed carb cleaner in the air intake and it ran as long as I was spraying the gumout,then It would die. My primary fuel water seperator is new and full of fuel. I took off the fuel filter on the generator and it appeared to be clean. There was no paper fuel filter as pictured in the manual. There instead, was a metal/brass colored filter. I could not get it to unscrew.....it turned but never unscrewed. I sprayed it down with gumout, filled the bowl with gas and fired it on gumout spray. This time it continued to run.
I thought all was fine, but the generator surged in r.p.m. as it ran. I found that if I hold the "on" switch (fuel pump switch) it will run smoothly. When I release the "oN" switch it begins to surge again?????? This happens with or without a load on it. There is no smoke and it runs smoothly while holding the switch.
Can the E-10 fuel cause this??????? It ran great on "real" gas.
The manual talks about a "gain" adjustment on the controller of the electronic governor.It says the gain adjustment affects the reaction time of the actuator to the generator/engine load changes. Would this need to be adjusted after switching to E-10 fuel?????(note in manual)- "A high gain can induce an oscillating of the actuator producing a hunting mode."The manual says this is mounted in the instrument panel??? I don't know where this is??? Is it under the panel holding the "starter" and "on" switches???
Any suggestions or help will be very much appreciated!
Thanks!
