Top-no-load RPM spec for Briggs opposed TwinII?

I need the top-no-load rpm spec for my setup to make sure it's adjusted properly (I had the governor lever off). The engine codes are 42A707 / 2653-E1 / 9812045B and the mower is a Murray 42509x92B.

SOURCE: up-front/top of engine clacking

The valve clicking sound in the 3.2 liter engine is a common occurance in most of the Isuzu Rodeo Engines. Some owners have spent money on expensive repairs to try and fix the noise, and some say that certain oils will make them quieter. Others have as many as 2 to 300,000 miles on these engines without a problem other than the clicking noise. Drive on.

SOURCE: Porter Cable 5500w generator (10hp BS) will not regulate speed.

While attending college I worked at a tool rental center and learned a great deal about matching generators to customer requirements and troubleshooting customer owned units. There are simple tests that you can perform, however, first some info on what to expect from a generator. Most generators are overrated and under powered. You should only expect to get about 60 - 75% of rating. Example, a commercial honda 5000w generator has an 11hp motor that can only produce about 9.5 hp at 3600 rpm. If a customer needed 5000w of power, we would rent them an 8000w generator because as the generator is loaded to max the voltage will drop. You generator will probably only provide steady voltage ex. 115v at 60 cycles to about 3500w then voltage will begin to drop. New generators have automatic voltage regulator that varies the power to the armature increasing/decreasing the power of the magnet. These voltage regulators suffer a high failure rate and are expensive. If your generator is not giving you 3500 watt at 115v 60 cycles your engine may have a few problems and your power generator end may need tweaking. (I would not expect to achieve 5500w at 115v with briggs 10hp) .
The governor is about 2 inches in diameter and turns off the cam gear inside the engine. It is flyball type with two or three small arms that react to rpm. The faster the engine turns, more force is applied to the governor arm to reduce engine speed. Easy to test, with engine running use finger pressure against the arm to increase speed and you should feel a greater resistance as the engine speed increases. Another simple test, remove air filter to expose butterfly inside the carb. Move the governor arm and check that the butterfly opens fully. If it does not open fully linkage and governor is not set correctly. Next, start engine and load generator up to max and check that butterfly opens to full as the load increases. When the butterfly opens all the way under load the engine is at max. Add up the wattage of all the tools/appliances you used to load the engine to get an idea of max load . Lets assume that the shop adjusted the governor properly, if the governor was not working the engine would over rev. and damage would occur. As you were told the governor spring controls speed and can be adjusted somewhat by bending tab or adjustment screw. But a review of your generator manual or that series of briggs engine will show that there are several governor springs available and different placement holes on the governor arm to attach the spring that will change the power curve. Pulling on the spring can only do so much, however changing the spring to different gauge /turns/material or differnet location on the governor arm will cause the engine to perform differently. These springs are sold thru briggs dealers by part number for your engine. This would be considered tweaking to get a different power curve.
Now for the generator. Some generators have a capacitor incorporated in the windings. This capacitor must measure within 95% of rating. Remove from circuit for testing. Finally look very carefully at the commutator rings for any evidence of brush bounce. If the brushes do not perfectly seat you will lose power. If your generator is brushless you can only hope that the diodes are within spec. because it is too difficult to test them. They also must be removed to test. Finally if your generator has an automatic voltage regulator the only test would be to replace with a known good part. At the rental center we stocked spare parts so that we could quickly find fault. There is soo much to learn and the life too short. I hope this helps good luck, please email your questions.

SOURCE: Briggs and Stratton Governor Linkage problem

The easiest thing for you to do is look at any 12.5-19hp Briggs single cylinder engine that's on just about any riding mower.. They all have the same set-up.

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.).

Revs to high


The throttle plate is spring loaded to pull wide open, opposed by the governor which will pull the throttle closer to closed when the limited or specified rpms are reached. If the governor arm does is not connected to the throttle bell crank(linkage broken, off, or missing), it can't pull the throttle closed. If the arm does not move to close the throttle, the governor is likely broken inside the crankcase. or needs adjustment. The internals are a spool that moves based on rpm, pulled up by flyweights that has the external governor arm shaft 'trapped' in between the spool 'ends'. The spool will move the shaft and in turning, move the arm to pull the throttle closed. You adjust the arm on the shaft so the governor can pull the throttle completely closed with all the slack taken up.

How do you adjust the idle on the Coleman 6250 Generator


There are many different models of Briggs used however simple methed is to find the governor shaft. Attached to the small shaft will be a lever with the governor spring and linkage that connects to the throttle. One end of the governor spring attaches to the lever and other is attached to either an adjustment screw with locknut or metal tab that can be bent. Increasing the pull of the governor spring on the lever will cause the engine rpm to increase. Bend the tab to allow for greater pull or adjusting the bolt with locknut. Make sure that the engine is not turning much more than 3600 rpm. Use a digital meter with Hz setting to set the output cycles at 60. When set at 60 cycles the engine should be turning about 3600 rpm which is where the engine develops max power.

I have a 7000 watts devilbiss gas generator. My question is: are the RPM's of the engine adjust to the load automaticly Thank you Walter


hi Walter
find the lever from the governor ..The lever has many holes.Make sure the lever is securely attached to the shaft where it exits the crankcase.On most air cooled engines,maximum speed is usually around 3500 rpm.If the governor is not working properly,engine over speed could damage the engine.Yes adjust the load automaticly. regards savumihai71

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
