Most generators use a flyball type governor within the engine to control rpm; also there is a voltage regulator that tries to maintain voltage at about 115v. The voltage regulator varies the voltage to the armature increasing /adjusting magnetic force. Use a meter with htz or freq setting to adjust engine governor to 60 cycles. When the generator is producing 60 cycles, the engine should be turning 3600 rpm, max power range. At 3600 rpm the voltage should be 115 to 120 volts. Loading the generator will cause governor to try to maintain 3600 rpm. Check engine manual for proper adjustment of gonvernor and linkage. The governor mech should last the life of the engine, however governor system does wear out. Expensive repair. enjoy

How to clean the carburetor?
normally the carburetor would have a fuel bowl fastened by a hex nut which will then have to be removed.some generators have a fuel solenoid which can also be underneath fuel bowl.once removed you will see a jet mounted either on the stem or in the stem.in the stem you'll will need a small screwdriver once removed followed by a fuel tube which has tiny holes that can easily be clogged use a jet cleaning rod,i use a strand off a wire brush works well,check float for sticking or clogged if so remove by pulling the rod ,open fuel valve too allow it to force any possible debris,re install all the cleaned parts and good luck.
