Newer tractor mowing the yard and the motor starts reving up and down my first thought was running out of gas but theres a half tank theres gas all the way to the fuel pump gas and air filtr is clean been wating two weeks for sears to send repair man they just called and changed my apointment for next month three more weeks so much for a warenty about 15 hours on motor
Its in the carb linkage which controls the choke and the throttle position..its just a pain to use it.. won;t hurt anything.
hard to imagine people still buy larger items from sears these days..sorry...

Hi
Two things come to mind. First it could be not getting enough fuel when hot due to carb adjustment being too lean. That could be that the float level in the carb is set too low or the low speed jet is set too lean. When cold the choke circuit in the carb supplies the extra fuel required.
Second in some enjines that have low compression they start cold but when hot the compression drops below 60 psi and makes starting very difficult until engine cools down.
I suspect a fuel problem.

I had a similar problem with a sears tractor. close to the carbarator is a rectangle box with a rubber hose going to the engine block - remove the hose and spray carb cleaner in the hose wait a few mins and try again - its a vacuum for the carb

SOURCE: Tractor starts then stop running
It will either be the stator that needs changing or the carb needs to be pulled off and cleaned

Sue your brother is right! I had the same problem and it turned out to be the gas cap. the small breather hole on the top was plugged with dirt. once I cleaned it out I took the rubber gasket out from the bottom of the cap and cleaned that as well. runs great now.
