I have a generator for my motor bike, but it has its own gas tank. 1850 Watt old style Coleman I was gifted. It took like 50 pulls to start before I cleaned the air filter, spark plug, and though not wanting to mess with the carburetor, that too. Now 1 or 2 pulls and it starts.
I saw that it was OHV type and if one day I want to take the engine for another motor bike build I might. An alternative is to take it back to Burning Man where I had it gifted to me and trailer it behind the motor bike dressed up as a fish. The electricity from the gen-set I could really light up the fish!
