Sputters & quits at proper RPM for engaging trans or mowing deck

Mower sat for 5+ years - cleaned carb, replaced all fuel lines, fuel pump (diaphram toast), plug, fuel filter, air filter. Motor starts fine and runs beautiful at low RPM but sputters and dies at RPM needed to mow. Breather tube is cleaned and open. Throttle linkage appears OK and choke is working OK. When I hold the choke in the perfect ''position'', I am able to throttle it up all the way with no problem. The minute I let go of the choke it returns to its preset fully open position and dies. Could this be a governor problem? Thanks for the help...

The jets may need to be turned a half turn in either direction while running, and then adjusted if they are gummy inside.

If the choke has an adjustment point, then adjust the choke to a good overall working powerband. If it still doesn't act correctly, look for vacuum leaks. If it is an option, you may want to install a manually operated choke lever.

My husqvarna yth2348 riding mower is havering carb issues not getting fuel


If this is a briggs and stratton they have a fuel pump on the front of the carb and ethanol plays havoc with the diaphrams in the fuel pump. I have to overhaul the fuel pump each year. Before you try anything else try "mechanic in a bottle" first. It is available at home depot, lowes, tractor supply etc. Just follow directions on the bottle and often it will clean out the varnish deposits in the pump and the carb both. Hope that helps.

The 12.5 murray 38 in runs fine until i engage the blades,while engaged the mower runs fine for about five seconds then starts to spit and sputter.once i disengage the blades it runs smoothly again


The problem is in the carb. First try using some bottled fuel system cleaner at a heavier dose than for a car, but be aware that too much may damage the carb. Then run the fuel out and fill with fresh and try again. When you engage blades and it sputters try to throttle down until it runs smooth and then slowly bring engine back up to mowing speed. You should be able bring it up and mow. Run out the fuel tank. If unable to do this trick and get the fuel system cleaner through you will need to have the carb. taken apart and cleaned thoroughly.

Am unable to start the mower despite new spark plug, new filter & fresh oil. Unfortunately I don't think I used all of last year's gas, although the mower acted like it was out of gas when I let run...


Do you have an in line fuel shut off that you turned off last year and forgot to turn on???
Try and remove the fuel line from the carb. If gas flows out you are getting fuel to the carb.If the above 2 items are ok the problem is in the carb..
I would try next to check for spark. Remove the spark plug and set it on the engine block or any metal. attempt to start , crank the engine . Is there spark?? If not and it is a lawn mower follow the spark plug wire back under the coverThe othe r end is connected to the coil/magneto Replace it . When replacing it ,you will have to gap the space between the coil and the flywheel. I use a business card.
If you have a tractor and no spark make sure the safety sw.s are working properly. Seat sw., brake/glutch sw?,deck sw. engage sw. be fore you change the coil/magneto.
On lawn mowers sometimes mice get in under the cover and nest. they will chew the spark plug/coil; wire.

Engine starts and runs fine, then dies.


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

Spitting and sputtering


mine did the same, I found out that the high speed jet was clogged, I pulled the fuel line off the filtor(going to the carb), stuck the line into a mixture of half gas half carb cleaner, I fanned it up and in 2 or 3 minutes it started running well, hope this helps.

Engine stops after ~ 15 - 20 min of mowing


try changing the spark plugs. if that doesnt work check the fuek lines for hole and leaks, check the fuel filter and clean if necessary. remove the carbuerator and inspect the gasket; it should be soft and flexible, if it seems hard or brittle replace it. clean the carb with carb cleaner sray (available at any local auto parts store) and compressed air. make sure you get inside the small fuel rail holes.
