The carburetor is probably clogged up. Mix a bottle of carburetor cleaner with the gas to see if that would help. Also check/replace the fuel filter.

You could have a bad or contaminated Mass Air Flow (MAF) sensor. You can get a used one online for less then 100. You can also purchase a can of MAF sensor cleaner at a local auto supplies store and clean it. It located right at the air filter housing.

You have dirt and/or moisture in your carburetor float bowl. Remove the bowl, clean it out, remove the main jet and clean it out and you should be good to go

Check your air filter to make sure it is clean, especially if the gen. has been run in dirty, dusty conditions. Make sure the gas tank vent is not clogged.

Also, pour some combustion cleaner into the carb. through the air intake to clean the carb. It sounds like it is starving for gas.

Hope this helps.

A big vavume leak and or the throttle blade doesn't close or it gone ( missing). the carb should close all the way ( you can't look thiugh it) with the linkage off you should be able to run it by hand with good results. if you can find out the correct way to put the springs on and just move things around or gat a look at one thats working right and you may see whats put together wrong on yours.

Why does my Ryobi 2200 watt generator surge at low RPM's


Engine governor sensitivity may be set too high, it keeps correcting too much, it's typical for all generators, 1 KW - 1 mega watts units.

Can i take apart the lower part of my briggs and stratton to repair my govenor?


Are you saying that it surges at full throttle and wont idle down or shut off? If so it is likely not a governor problem. Surging is a lean condition. Some models, particularly yard machines, will surge no matter the adjustment unless under a load. If it were a governor issue it would run faster and faster beyond full throttle. IF it wont idle down check the throttle control and throttle linkage and check for a sticking throttle shaft before suspecting governor. Not shutting off could also be in the throttle control. A ground clip is in the control. if the tab is not engaging the clip or the wire is not connected then the motor will not ground. Check those things before messing with the governor, especially if the machine was running good and no one has messed with it yet. Governors don't just come out of adjustment by themselves.

Hello, my Briggs & Stratton generator, PP5000, Intec, 8 hp, Model 202412, type 0167E1, has lower power output, 180 Volts in stead of 220-230 Volts. Any idea where I should look ? Engine is 8 years...


Hi and welcome to FixYa. I am Kelly

Usually when you have a lower voltage output that is yet above 150 VAC the problem is as simple as the engine is no longer running at full speed. This could be caused by binding carb or governor linkages but more often than not the Governor adjustment screw has backed off over time causing the engine to gradually slow so the output voltage drops. The user does not notice it so much until the output drops more than 15% and you notice dim lights... slower running equipment etc.

Look for a circular plate / governor speed plate near the base of the governor lever but off to one side that has a spring that attaches to the governor lower end of the governor. There should be a screw with a locking nut. Loosen the nut and turn the adjusting screw clockwise to increase engine speed. (You may have to barely loosen the pivot nut on the governor speed control adjustment plate to make the speed adjustment.... tighten when done with speed adjusment) Watch your output voltage and adjust the voltage to 225 VAC with NO LOAD. The voltage will drop as loads are added. Make sure to tighten the lock nut on the adjusting screw or in a matter of an hour you will have low voltage again from engine speed dropping. What ever you do.... DO NOT adjust the governor arm base attach point where it attaches to the engine.

Just so you know a weakened governor spring can cause the speed drop also. If the speed keeps dropping with extended use, you may have to change the spring that goes from the lower end of the governor arm to the governor speed adjustment plate.

Governor does not seem to work


Sometimes the governor gear inside the engine breaks and you have to replace it. Did you try to adjust the governor by putting the throttle full and unloosen the screw on the governor arm and push the governor piece the same direction as the throttle opens and tighten the screw.

7 hp brigs engine on my generator runs two fast producing 127 volts. how do I slow it down?


Hi and welcome to FixYa. I am Kelly. Since you did not mention the make or model number of your generator I will respond in generic terms. If your generator is at 127 volts with NO load it is adjust at the very top end of the manufacturers limits. There is a 10% tolerance so 120 VAC + 12 is 127 VAC. Under an electrical load above 500 watts the generator should drop the output voltage slightly so your generator would still be within factory limits. Personally on any generator as a repair person; I set the output voltage at 126 VAC no load so that when the user puts the generator to work the output voltage is good. If your generator is running at 127 VAC under load then you can adjust the governor screw on the governor plate CCW about 1/2 turn to drop the voltage. Without a generator model number or engine number I can not tell you exactly where the governor plate is on your engine / generator. The screw will have a lock nut that you must loosen 1/4 turn then turn the adjustment screw CCW to drop the voltage. Just make sure to re-tighten the lock nut when the adjustments are complete. Mind you by decreasing the output voltage you also drop the output freqency at the same time you decrease the output voltage. It is better to have 125 -127 VAC under a no load condition as the more electrical load you add the more voltage drop you will notice. It is best to adjust the generator to 122.5 -123 VAC under a medium load. (50% of output capacity) A bread toaster is 1400 - 1600 watts and is a good load for a 3000 watt generator. Also a good hand held hair dryer will use around 1600 watts. If you use this type of load and the voltage output is 122.5 to 123 VAC I would not adjust anything. I have been working on generators since 1970 so this is nothing new for me. I hope that you understand everything I posted. If not, feel free to ask as many questions as you wish in any future response.

Motor is running eratic up and down under load


One of the most important parts of your engine is the engine governor. An improperly adjusted governor can shorten your engine's life. If engine speed is not controlled, the engine will destroy itself. Never run an engine over speed, especially without a load attached to it. Even for a short period of time it can cause catastrophic failures, like blowing the magneto magnet into 100's of little pieces. Over speeding is something that needs to be taken care of immediately, because it can be a real hazard with metal coming loose at high speed. This page will explain how to adjust the mechanical governor on Briggs and Stratton and Tecumseh Engines.
First, let's understand a little more about governors and why they may not be working right:
Most complaints about governors fall into two categories:
  1. Engine runs too fast or too slow.
  2. Engine surges or hunts.
You should do an inspection of the governor linkage and spring before trying to solve either of these problems. Make sure everything is operating freely and the spring is not damaged or stretched. Also, check the governor static adjustment to see that all free play has been removed between the spindle and carburetor. The best way to do this is to move the throttle from idle to full open and note the way the governor shaft moves. If it goes clockwise, then loosen the clamp screw and with the throttle wide open turn the shaft all the way clockwise and re-tighten the nut. Make sure the throttle moves from idle to full open freely after making the adjustment. Refer to the engine repair manual for exact adjustment procedures.
After you have made the above check, restart the engine and see if the governor now operates correctly. With the engine at idle, move the governor lever with your finger to open the throttle and it should push the arm back toward idle if working properly. One way to do this test is with the governor spring removed. If it still over speeds or has no push toward idle, you probably will need to have the internal parts checked inside the motor or recheck the static adjustmen

The govenor rod cannot be adjusted. The springs are intact. Motor revs up but will not idle down. It is 23 HP.


Just guessing here, but if there is no control of the throttle and the engine over revs, then more than likely the governor control is broke. Briggs if famous for that problem. Governor is around 25 dollars and a lower crankcase gasket. Requires the engine to be pulled, lower crankcase removed, remove all pieces of old governor and then re assemble with new governor and gasket.////Before doing all this check that both springs are on the governor on the exterior of motor. If you manually hold the governor arm back, counterclockwise, and it still revs, then you need to replace governor. Don't let it rev for long or it with throw a pushrod or worse. good luck

Back firing, load engine noise, engine skip


Could use more info but here are some things u can check--Plug wire grounding to block, old spark plug--check head bolts for correct torque--carb adjustment or jet plugged-governor linkage not hooked up or improper adjustment of governor--if these are good then it could be internal--bad valves and valve adjustment--timing gears

SnapperLawn Mower 8 hp Tecumseh engine runs only on high speed.


Hi

first check the governor linkage.The link with the governor sistem from crankcase is the lever(arm) with some holes.To encrease the sensitivity, raise the spring into the next higher hole in the arm.To descrease the sensitivity,hook the spring into a hole lower than its original position.If you need more info just tell me.
