Question about Generac 5724 GP Series GP3250 Portable Gas Powered Generator

Open Question

The governor does not keep the engine from over-revving. I removed the linkage at the governor shaft, and when it over-revs, it makes no attempt to correct it. Is it hard to dis-assemble the generator head from the engine? I do all my own repairs, but was told today that this requires special tools from Briggs and Stratton -- any thoughts? Thanks! Chuck

Kohler V-Twin (624 cc) RPM on the engine does not stay stable , It will raise and lower the RPM in any Throttle Range. Could the Governor be going bad???


Try a static governor adjustment first as it simply be out adjustment.

Static Adjustment Procedure
Make this adjustment whenever governor arm is
loosened or removed from cross shaft. Adjust as follows:
1. Make sure throttle linkage is connected to governor
arm and throttle lever on carburetor.
2. Loosen nut holding governor lever to cross shaft.
3. Move governor lever toward carburetor as far as it
will go (wide open throttle) and hold in this position.
4. Insert a long thin rod or tool into hole on cross shaft
and rotate shaft clockwise (viewed from end) as far
as it will turn, then torque nut to 6.8 N·m (60 in. lb.).

Why does engine run at full trottle only?


Mark it sounds like there may be a problem with the air filter. If its revving and running to fast all the time clean the air filter.

Governor settings for 18.5hp B&S single cylinder,31E777-2439-B1 Husqvarna


The governor shouldn't need to be adjusted unless it has been bumped or removed. But, if your sure the problem is the governor, you adjust by moving the governor arm in the direction that opens the throttle valve all the way open. Remove air cleaner and filter to inspect while doing this to make sure. Then note that direction, keep in this position, then loosen small nut on governor linkage at base of unit. With a needle nose pliers, turn small center shaft of governor linkage(the part that leads inside engine) in same direction you moved the linkage in earlier step. While holding in place tighten small jam nut. This is called a static set, which is a factory standard. Also, make sure throttle cable is in wide open position when doing this. Good luck.

Champion 35 Classic lawmnower with a 3.5hp briggs and stratton engine. Engine starts fine but will not run regularly.Keeps revving and then dying back and then revving again continuously.


Check the governor spring and throttle linkages, something may have come adrift. Also check the throttle shaft and body for wear and excessive clearance which could **** in excessive air, upsetting the mixture.

It runs wide open all the time im wondering where idler arm setting is at


It sounds like the govenor spring has become disconnected or the clamp on the governor shaft has become loose and allowed the linkage to get out of adjustment. If problem has occurred suddenly it could mean the governor gear assembly inside the engine has broken and means the engine will need to be dismantrel to replace the governor gear assembly.
Check throttle linkage to see if spring is attached at both ends, one end on the throttle linkage and the other at the fixed point on the engine or to the end of the speed control lever. With engine stopped the spring should hold the throttle wide open and hand pressure on the linkage shoud be all that is needed to move throttle shaft closed to the idle position with no binding in the movement of the linkage.
If spring is OK and while engine is running, linkage should be able to be be moved to bring engine back to idle. If porblem has occurred gradually, then linkage will need re-adjusting. Loosen adjusting clamp on governor shaft, then holding linkage in wide open throttle position rotate shaft as far as it will go in the opposite direction to that requred to close throttle to idle . Re-tighten clamp.

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

Think i have a problem with governor on my 21hp v-twin briggs. it jumped to max speed and can't get it to slow down. which part of the governoring system could have let go?


Check for a broken spring on the governor linkage, follow your throttle control cable down to where it attaches to the throttle mechanism. In behind where the cable attaches you should be able to see a spring on the governor arm, the spring may have broken or somehow came out of its attaching point. Obviously be very careful about over-revving the engine, it could result in a broken connecting rod and a hole in the side of your crankcase.

10 hp briggs runs at high speed, govenor don't seem to be working


One possible cause for this problem is debris,sticking,or frozen linkage between the governor and the throttle butterfly. Depending on the make and model of your engine it will either be a mechanical governor that has a arm that goes down into the case or a air vane governor that is behind the recoil shroud of the engine. Move all the linkage that connects between the governor and throttle and speed lever to make sure it doesn't bind or sticks. If it does pray a little silicone or wd 40 spray on it to help reduce friction. Also on air vane governors they can become stuck from debris that inhibits it from moving make sure there is nothing in the way of the governor. If all of the linkage is working properly and you still have the issue try adjusting the the fuel mix screws and the high rev. settings on the throttle lever (if equip.).

Engine revs wide open when starting


Check to see if the throttle shaft on the carburetor is actually moving (with engine off) Does it slow down when you move the throttle control on the dash?
Start it up and try moving the linkage on the governor shaft, if there is little or no resistance but the engine slows when you move it, most likely you have a broken governor gear inside the engine. Another possibility is that the screws that hold the throttle plate to the shaft have come loose and the plate is jammed in the throat of the carburetor
