Question about Briggs & Stratton Briggs Stratton Intek V - Twin Vertical Ohv Engine with Electric Start 22 Hp, 1" X 3 5/32" Shaft, ModelNo. 44K777 - 0027 - E1
The engine starts easily, but the governor pulses the revs continuously whether it is hot or cold. I am using fresh petrol; I have changed the spark plug. All the linkages are clean and move freely. I have taken the carb off and looked inside. It is very clean, with no deposits. The main jet is clear, and I have **** the bypass jets, though I can't see how to check them otherwise. If I hold the governor lever still, the speed is fairly constant, though it does sound a bit rough. Any ideas would be welcome please! I have a 22hp briggs intek twin and it pulses and misses at full throttle
Just adjust the idle speed control/Fuel air screw located pointing downward on the bowl of the carb,Just start the engine,idle up high and turn the screw until it levels out and runs smooth.

If you have removed the main jet and made sure it is clean(unscrew it from inside central tube), remove the throttle stop screw (brass screw on top of carb) revealed is a brass screw top, unscrew and make sure that the pilot jet inside is clean, blow through it with foot pump fitted with a rubber seal (tyre valve), if you have cleaned it all thoroughly it will run after refitting all, make a physical note just where the throttle stop screw is (how many threads are visable) before removing so you have some idea where it should be screwed back into. Its starving of fuel due to dirt. Always but always turn off fuel at the end of mowing and run carb dry otherwise fuel evaporates leaving fuel debris that then binds together to block your jets

Me and a friend both had this problem with our mower, they would only run on high speed and would pulse or surge at idle. Tried cleaning the carb but that didn't work, tried replacing all the gaskets, no improvement. Bought a new carb from a Honda power equipment dealer online for a whopping $16, along with the governor spring and rod, spent about $31 total. Installed the new carb and it purrs like a kitten, idles, runs on any speed, just like new. I did also move the spring on the lower right that attaches to the governor lever from one hole to another. Seems the carb and associated linkage is very touchy, that's why I replaced the other parts but the carb may have had a clogged jet and I just didn't feel like messing with it so replacing it did the trick for me.
