Looks like I'm going to have to pull the generator to replace the starter. I can manually turn the engine and it turns freely. The starter solenoid seems to be working good, and the voltage is getting there, but all that happens when I hit the button is the solenoid "CLICK" and the fuel pump running.....but not turning the engine. Gotta plan another day with a couple friends, some bottle jacks, and boards to slide the genset out so I can get to teh starter to replace it. Guess that'll be a good time to do all the other servicing too.....
