Question about Electrical Supplies
Engine speed change
First verify that the breaker for the outlets is not tripped and make sure that the generator is running at full operating speed. let it run for 5-10 minutes and check for output power. If there is nothing, there are two possible problems. One could be that the automatic voltage regulator is bad. The other is that the field needs to be flashed - a high possibility if the generator has not been run in a long time. There are many videos on the internet that show you how to solve both of these problems. Just do a search for No output from a portable power generator.

SOURCE: Low voltage
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

You have to find the governor linkage.There is a spring adjusting by a screw to increese speed to get more power.Try to locate it.

Speed, unless VERY low will not cause your problem.
You likely have a failure in the generator section.
You need to determine if the unit is a permanent magnet rotor or a brushless type. IF it is a brushlesss type with rotating diodes on the rotor, it is likely one of the diodes has shorted. Also the capacitor across the regulating winding may have gone bad. either shorted or open.
You need to check the voltage.you are getting out. Unfortunately, mist meters will not read correctely unless the wave is sinusoidal and if a diode is out, the waveform will not be.
If the unit is a permanent magnet type, you may have a shorted field winding.

Depending on the engine, you will find an arm attached to a small shaft coming out of the engine block. This governor arm is where there is attached a governor spring and the linkage going to the carb. The governor spring is attached to the arm on one end and to either a bolt or a tab of metal on the other end. If attached to a bolt, you will find a lock nut and enables you to increase tension on the spring (pull harder) thus increasing engine speed. If you have a metal tab, by bending the tab away from the spring, you will be applying more tension. You will not be bending carb linkage. Before you make any changes, find a meter that can measure Hz . Plug the meter into house plug and notice that hz reading will be 60 cycles. Then read voltage at house plug, could be 115 thru 120 or higher. Your generator produces 60 cycles when it turns 3600 rpm. Before you make any adjustments, plug meter into outlet and check hz. If reading is at 60hz, the engine is already running at max indicating problem with actual generator parts and not engine running slow. If cycles low, adjust by bending tab pulling harder on the gov. spring, or adjust screw to pull on he spring. In either case, adjust a little and re-test. With engine running to produce 60 cycles, the voltage should be between 115 thru 120. Some generators have an adjustment screw to increase voltage on the voltage regulator inside the gen set.

SOURCE: gnerator not producing ac power
I recently had a similar problem during "Sandy". I forgot to turn off the hot tub before starting the generator and the house lightswhere barely lit, dim, and flickering under the load. I quickly shut itoff andthe hot tub, but not before frying half of my generator. It will only produce 110now, not the 220 usual adn I need to get it fixed. I imaging you may be experienceing the same thing if you can't reset it. My generator has two reset buttons right next to the outlets on the unit itself.

It is quite normal for the exhaust manifold and turbo to get very hot, especially when the engine is working hard running at high speed under load. Every time the mixture in the cylinder is ignited there is a small explosion producing a BIG flame and a lot of heat to push the piston down. A lot of this heat goes out the exhaust. During daylight it is usually not noticeable, but at night it will visibly glow up to a bright red.
In relation to the oil pressure dropping, providing the oil level is at the correct level, there may be a restriction in the gauze filter on the input of the oil pump due to sludge buildup. Once the engine warms up and the oil thins out, the oil pump can't work at maximum capacity. The drop in RPM could be caused by the turbo getting insufficient lubrication and cooling due to the low oil pressure reducing oil flow to the turbo causing it to not work at its optimum speed and efficiency and therefore through reduced air flow into the cylinders the engine would tend to loose speed especially when under high load. The drop in RPM could also be caused by a problem with fuel flow to the injector pump causing the engine to run lean which would not allow the engine to produce maximum power and also contribute to higher exhaust temperatures because the governor would have the throttle wide open to try and maintain the engine speed when the generator is required to produce maximum output.
