TOOK CARB OFF TO CLEAN OUT "GUM" FROM SITTING. DURING RE-ASSEMBLT SOLID 1/16" ROD FROM GOVERNOR ARM TO THROTTLE PLATE ARM HOOKED UP OK. THEN I DISCOVERED A VERY LIGHT WEIGHT SPRING AROUND ROD WITH A HOOK IN EACH END. THE ONLY TWO PLACES THIS OBVIOUSLY WILL HOOK UP TO IS THE SAME GOVERNOR ARM IN HOLE NEAR WHERE SOLID ROD CONNECTS AND IN A SECOND HOLE IN THE THROTTLE PLATE ARM. CONNECTED THIS WAY, LIGHT WEIGHT SPRING DOES ABSOLUTELY NOTHING. GENERATOR WILL AND START AND RUN ON FULL CHOKE, BUT YOU TAKE CHOKE OFF AND ENGINE RUNS EXCESSIVELY FAST AND DIES. IT SEEMS THE GOVERNOR ISN'T CONNECTED PROPERLY. HELP

Might want to check out the carb it sounds as if the machine may have been sitting unused for a while. Carbs are small and get gummed up from sitting. You should always use stabilizer in the gas if sitting for long periods of time to avoid gumming up.

Solid wire linkage from governor to carb throttle shaft. Spring link from user throttle plate to governor. Throttle cable connects to arm on throttle plate.

As a rule there is a rod that runs from the governor arm to the carb throttle plate arm, sometimes there is a lot of holes to choose from to put that rod into. For most mowing type settings you push the throttle wide open on the carb and push the governor arm all the way full throttle and connect the rod by using whatever hole will let you or bend the rod to get into a hole. Your throttle cable will be connected to the governor arm with a spring ,this will allow the governor arm to swing back and forth to hold a steady RPM that you selected with your throtle cable. In a non mowing application like generators, the voltage output is regulated by the RPM so it would be adjusted by using a voltmeter and setting the governor to get 120 volts 60 cycle at the plug in, In the USA. Without the make and model it is hard to do more then talk theory but if you're handy this info will help.

Looks like on page 30 there is a picture of the rod that attaches to the governor and carburetor. Over the years of working on engines that someone else took apart I found that to hook the govenor tom the carburetor the rule was pretty much the same on all except generators. Some have more then one hole to choose from some you just bend the rod but one thing is the same , /// With engine not running,,,You push the butterfly wide open throttle on carb then go down to the Governor arm coming out of the engine block and turning it the same way you twisted the butterfly arm on the carb all the way,in your mind think about clockwise or counter clockwise, if facing it and you turn the carb butterfly arm clockwise to get it to wide open you will need the same thought when facing the governor arm then connect them together with a rod/stiff wire. If when your done it seems a little soft and pulls down you can take your needle nose pliers and put a small z bend in the rod to get it tighter ,quicker to raise the rpm's under a load.

It still sounds like a carburation issue. Are you sure all jets, vents and ports in carb are open? Another possibility is that the governor setting is off. The governor is the rod that comes out of side of engine and connects to throttle linkage on carb. To set governor to factory setting, push governor linkage in direction that opens throttle valve, loosen screw on governor arm and turn rod in same direction until it stops, while holding in this position tighten screw on governor arm. This is called a static setting. If this doesn't work I would disassemble carb, remove all plastic and rubber parts and soak in carb dip overnight. Picture may be different from your unit but it shows governor linkage to carb. Good luck and happy wrenching!

These can be tricky, but your on the right track. With throttle set on high (engine off), turn governor linkage in the same direction that opens throttle valve in carb wide open, then turn the governor rod in that same direction then tighten bolt on governor arm. This is a static setting. The high and low idle is most likely a dirty carb so assuming the carb is now clean your idle should be better. Hope this helps. Good luck!

Ron:

If the mower starts easily and runs well but surges, the problem is not your carburetor! There is an arm coming from the crank case that links to the carburetor throttle arm with a small rod (the rod has a spring around it). That is your throttle governor. Loosen the nut where the governor arm meets the shaft going into the crank case, set the throttle to full throttle and using a pliers, twist the governor arm (coming out of the crank case to full open (twisting the shaft in the same direction that the governor arm would twist it when you go to full throttle). Tighten the governor arm nut without changing that setting... don't let the governor arm move or let the governor arm shaft (coming out of the crank case ) move or the setting will be wrong. ( I know... a third hand would be useful to hold the governor arm to keep it from moving). You may have to make that adjustment a few time to get it right.

the solid wire link goes from the top hole in the governor rod to the carb and the spring goes from the lower hole on the rod to the throttle plate where the cable attaches

Hello rebel_auto:

>>Send me the Make, Model and Type or Spec Numbers Off the Engine, Please. With these I can Locate the Proper Manual and Better Assist you.
However, this File may Help.
**The Throttle Cable Attaches to the Throttle Control Bracket. The Cable Moves a Slide that Moves a Pivot. The Pivot has the Spring Attached to it and the Other End of this Spring Attaches to the Governor Arm. The Solid Link Connects to the Governor Arm and goes to the Throttle Shaft on the Carburetor. When the Throttle Cable is Moved it Moves the Pivot and the Pivot Pulls the Spring. The Spring Pulls the Governor Arm and the Governor Arm Moves the Throttle Shaft. Usually the Spring is in the Lower Hole in the Governor Arm and the Solid Link is in the Top Hole of the Governor Arm.**

Hello:

The Carbuertor Throttle is Held in the Full Open Position Until the Engine is Started and Running, then the Governor and Spring Work together to Keep the Engine RPMs to the Desired Setting.
The Following is an Explaination on How the Governor System on Small Engines Function.
>>The Governor System behaves like an Unending Tug of War between One of Two Governor Springs, which Pull the Throttle Toward the Open Position, and a Spinning Crankshaft, which Tries to Close the Throttle. When the Load on the Engine Increases - a Typical Example is when you Move your Running Lawn Mower from the Driveway to the Grass - Crankshaft Revolutions Drop. But the Governor Spring is Still Tugging, Causing the Throttle Plate to Open. In Response, a Larger Volume of Air-Fuel Mixture Enters the Carburetor, Increasing Engine Speed to Compensate for the Increased Load. The Crankshaft Speeds Up, and the Tug of War Resumes, until a New Equilibrium is Achieved. With Each Change in Load, the Tension Between the Governor Spring and the Load Brings about a New Equilibrium, known as the Engine's Governed Speed. Neither Side Wins until the Engine is Shut Off. At that Point, without the Crankshaft Spinning, the Governor Spring Pulls the Throttle to the Wide-Open Position. Two Types of Governors are Common on Small Engines - Mechanical and Pneumatic.
