Hard starting Generator?

Question: What can cause hard starting on an Onan 7.5 KW generator? Could it be the Glow Plug?

Dave’s Answer:

Before you go after the glow plug, I would suggest fuel filter on bottom of gen set. Next thing I would check is the rubber fuel line for cracks right next to clamp going to gen set engine. I have found with gen sets the rubber fuel over time will crack next to clamp that holds in place on the steel tube.
