Any suggestions. I just bought this MH and was told gen did not START.
Thanks and God Bless Ken
The solenoid does one thing only— it slides the gear on the starter to engage the flywheel. The starter motor still has to turn for anything to happen. So, not only do you need power to the solenoid, you need power to the starter motor as well.
If you HAVE power to the starter motor as well, then the next step is to remove the starter to test it on a bench. Which may lead to replacing it or getting the motor rewound.
While you're at it, you ought to pull the carburator and fuel filter— clean the carb and replace the filter. Once you've got the starter working, there could still be a problem if ethanol gasoline was left to sit in the filter and/or carburator bowl. Ethanol is hydrophilic, and attracts water from the water vapor in the air. Combined with phase separation of old fuel, you end up with gummed-up carb and/or filter. Since you don't know how long ago it was that the generator actually did work, it's a safe bet the gas in it has gone stale.
Also pull the spark plug and rotate the crankshaft by hand, if you can. This will ensure that the cylinder isn't full of stale fuel.
