I'm interested in figuring out how the governor works on my self propelled Honda lawnmower. I have a Honda HRX217HXA mower. Is the governor controlled by some sort of vacuum that is generated from the mower itself, or is it a mechanical device that does this. I'm asking this because I seem to be having a problem with my lawn mower idling when the blade is not engaged. I have removed and cleaned the jets with a compressor, but still when the blade is not engaged the idle goes up and then down and repeats this cycle until I engage the blade. If anyone has any ideas or can explain how the governor works I would greatly appreciate it. Thank you!

The lawnmower only has less than two years of light use on it. I looked at the maintenance manual and it shows the governor with some sort of weight system. I'm thinking that this is what the second answer is referring to. If that's the case, what is the likelihood of something being wrong with the governor and not carburettor? If it was the governor that was causing the erratic idle, would this also cause the same condition when the blade was engaged? As far as taking apart the carb, I ensured that both the low speed and high speed jet were completely open. I completely took the high speed jet out and checked to ensure passages were completely open. I also ordered new gaskets for when I put the carburettor back on. I also removed the fuel tank and all of the fuel lines to ensure that there was no debris in the fuel system. I'm looking forward to putting it all back together when the gaskets come in, properly adjusting the idle, and seeing if that makes any bit of a difference.

The governor work off the fly wheel. The fly wheel is on the top of the motor and has vanes on it to circulate air over the motor to keep it cool. The governor sets under the top cover on the motor and looks like a weather vane but with a spring and linkage. When the motor blows air against it to moves to control the motor carburetor to keep it from over revving.
The spring might be getting weak, or the speed is a little to high. Reducing the engine speed when the blades not engaged, it should stop doing this. This problem is common, and is nothing major. It stops when the blades are on because it brings down the speed of the engine.
Good Luck

On some engines the governor is as described by the first answer. On others it is internal and uses counter weights. In either case a bad spring could cause the issue. I do have a problem with the way you described cleaning the carburetor. It should be fully disassemble, soaked in a good quality carb cleaner, not the spray type, rinsed, blown out with air and inspected to ensure all passages are clear. It should be be reassembled using a rebuild kit. The problem is the engine is trying die and the governor is trying to keep it alive. This causes the surge in rpms. Most likely plugged idle circuit.

Its called 'Hunting and surging" and there are only a couple of causes. It could be the governor spring. The governor fights to keep the engine at low idle, where the throttle wan to open the engine up. The other factors are the fuel line, the air supply and finally the carb itself. Just blowing out the jets is not good enough. It needs to be thoroughly cleaned. All it takes is a grain of sand, and the carb is screwed up. Taking it to a dealer for the carb is the best bet, but check the others first.

On most you just loosen one screw then adjust the engine speed to what RPM you want then tighten the screw. It is however not really good for the engine to increase the RPM too substantially.
