bought a 98 murray briggs & stratton 12.5 - good looking old mower/clean. I cleaned the carbrueter but can't get miss out when i engage the mower-worked once but when i got on a hill and called for gas-same thing again-filter is good and thought carbrueter looked ok-could it be governor-any suggestions appreciated Tom in Ky

Put an in-line spark tester to determine if it is a fuel problem or a spark problem when this happens.

Try a new spark plug...maybe a different brand.

Hi and welcome to the forum! :smile:

I am moving your thread over to the Murray section to see if we can get you some more answers.

I don't see anything wrong with answer already given.
To the op I used to have a 98 Murray also.

i got a plug-it had different plug in it for something-don't know what - i will let you all know and thanks for the help. I am always open for suggestions - I have older mtd and my cousin's old john deere to mow his yard with when i can-they both are doing ok but i want this murray because the old mtd is about used up - THANKS AGAIN TOM

Try running a couple of ounces of Sea Foam added to the gas tank. Also I rebuilt a carb on a mower a couple of times and never got it to run right. Found a carb on line and the mower runs great now, the old carb must have had a pin hole or something in it as it acted like it was starved for gas but the gas flowed right to it. Also check the intake manifold to make sure it is tight with no leaks as well as the carb to manifold connection.
