I got a Buffalo Tools Sportsman Portable Gas Generator with 1,500 Running Watts, 2,000 Peak Watts. the valves on the motor are very loose. how do i adjust them?

try googling buffalo tools 7,000 w propane generator manual

7000 kw is a very large unit - 7,000,000 watts

Edited for clarity and moved from Cars to Generators.

Valve clearance goes by the engine, not by the generator maker. They are usually Briggs and Stratton, Honda or Kawasaki.

Can you provide more detail on this? Such as under what conditions it overloads, and how much power you're drawing off of it? Keep in mind that generators have two ratings: Sustained Load and Peak Load. Mine, for example, can handle a sustained load of 1,750 watts, and can handle short-term peak loads of 2,000 watts. Note also that if you're running a microwave, they take a lot. So does anything with a motor in it (refrigerator, etc) on initial start up. Once you've added up all your loads, adjust to where you're within your generator's sustained load and you should be fine.

Could be lost exciter current. This is how to restore it - Connect 16 or 18 gauge wires to a 12 volt battery. With generator running, insert bare ends of wires into AC outlet - one to Hot, the other to Neutral. Insert and remove quickly. There should be a flash and power will be restored. If not, repeat until you get that flash and output current restored. Using light gauge wires is so that if you are too slow to remove them once AC is restored. they will burn out before the battery suffers from the AC incoming. Be quick and be careful.

Assuming the speed is correct check the voltage on the rotor brushes during running (Caution) It should be DC. If you have low or no DC voltage then the capacitor in the end of the generator housing is bad, or the AVR. If you do have voltage then make sure the slip rings are clean and shiny, from there you may have a rotor or stator issue that needs carefull resisitance check

Take the plug out and go to Home Depot. Buffalo Tools makes that unit and Home Depot is a seller

call buffalo tool parts dept.they have brand new tanks for $36.75 or if you need a petcock they cost $9.95 they also have the gas gauge for $9.60.call 1-800-568-6657

There have been several factories in china that have made the motors used on buffalo generators, a couple of these are Lifan and J.D. as in Jiangdong.All of these motors are very similar to honda motors.The 6.5,13,and 15 h.p. motors are real brutes and hold up very well.

Idle speed jet or passage and/or high speed jet/passage is clogged. Remove the carb and inspect and clean thoroughly, then re-install. Set idle and high spped screws approx 1 turn and tune to run smooth from there.
