Question about Mtd 22" Yard Machine Push Mower

2 Answers

Engine starts and runs fine, then dies.

I have a MTD 22" push mower that starts normal and runs great for about 30 seconds, then gradually the RPM drops off until it dies. This takes another 30-45 seconds. if i wait 2 minutes I can start it again and it does the same thing. [The yard takes forever to mow this way!] So here is what i have done. First i replaced the fuel pump (a rubber diagram and gasket that go between the gas tank and carb) the same problem. so than i ordered a new carb and installed it. it came with another fuel pump and gasket which i also installed. Same problem. The gas tank is clean and free of debris, that vent on the gas cap is clean and freely flows air. The air filter is clean and the mower does the same with it installed or not.

Any other ideas????!!!!

I have the same problem as NOZUALM with the same model B&S, type 2286. Hope a carb rebuild kit will solve problem. This is a "self-governing" engine; no carb adjustment nor accellerator lever. jlp0901@cfl.rr.com

My 5hp B-S is doing the same thing and found a post that seems to be the best answer. Replace the float. It runs out of gas if the float is not working properly.
Another cause may be the diaphram, maybe.
Mine is 12 yrs old so I plan on getting the whole carb rebuild kit
while I have it apart
Good Luck

I have a Yardman 22" push mower Model 11A-084E029 B&S 158 cc engine I bought new. It starts and rungs great the first time I use it. When I go to use it again in a couple of weeks it will not stay...


still your gas could be not good for a small engine like a push mower. check your local content of ethanol in you area. ethanol is very,very,very bad for small engines. ethanol(alcohol) over time creates moisture in the gas and moisture(water) dont burn. I say check you local gas station or go buy gas other place. look around for special gas like for fleet. empty all gas and remove carb. bowl and fill with new gas.

My mower starts and stays running for about 5 seconds then quits..has gas and oil any clues


Check gas line. Check for a gas filter and replace it. Replace spark plug. If the prob continues - it might need the carb rebuilt.. If a small engine sits to long without being run - the gas will shellac in the carb and render it to not function properly..

have a great day !

Push mower runs for 3 seconds and dies brand new mower used it 2x


If the carb mounts directly on top of the tank chances are the diaphram gasket between the carb ant tank has swelled and needs replaced

Can't keep mower running without consistently pushing the primer.


It sounds like there is water in the gas. The only way to remedy this is to take the carb off of the gas tank and replace the diaphragm, there is a small reservoir between the tank and carb...clean with WD-40 to remove water

MTD Yardman push mower runs fine for awhile then cuts off.


Try buying a new plug first but if it continues then I would say that there is debris in the carb.
