Kayteg, I had the same problem with my 36LP a few years back, and eventually discovered that the "regulator" on the generator wasn't operating correctly. That device is not really a regulator. It's more of a vacuum actuated on/off valve that is supposed to open when there is the tiniest amount of vacuum in the intake manifold. As it ages though, the rubber seat on the needle valve inside it gets sticky, and refuses to open when the engine is cranking.
Wouldn't it be great if there was a way to manually force the valve to open? Guess what......there is!
The OP in this topic had bigger problems with his than you do, but in my post you will find a link to the US Carburetion website regulator page. Buy the replacement for the KN regulator that has either a manual prime button or an electric prime solenoid.
After you install the new regulator, the way you use it is to push and hold the "Prime" switch on the generator panel with one hand, and then push the manual prime button on the regulator with the other hand. I usually give mine a couple of one-second shots, then hit the start switch. It cranks 2-3 seconds then starts every time.
Provided you don't have other issues with your gen, you will love the way the new regulator helps it start.
