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.

My mower will die everytime i engage the blades to mow


Check to see if one of your deck spindles isn't seized. Disengage the blades and turn each blade to see if its free. Sounds like either a spindle is seized or your electric clutch on the motor has a problem.

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.

I have a Sears 42" deck mower. It keeps stalling. Sometimes uphill but also on level ground. Gas in filter is present yet just shuts down. What could this problem be?


Most likely this is a fuel pump problem or a float problem in the carburetor. Most carburetors can be cleaned and rebuild but most owners will not
have the proper equipment to do a thorough job. Take it to a good
servicing dealer for his advice and estimate. Sometimes there is a
gasket or a valve problem and a good experience mechanic can
tell a lot by just listening to the engine for a few seconds.

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.
