k181 fuel pump

Recommended Posts

ok so ive been having a fuel issue for a while so what happens is that it runs fine for a couple hours then it dies like just dies doesn't bog downb and die it just dies or you shut it off then it doesn't start again and i clean the carb that's brand new its a i save tractors carb and then it works for a couple more hours then bam same issue and i just keep cleaning the carb even though it dosetn seem dirty and then i put on a 75 micron fuel filter from kholer and flushed my tank and still this persists and i pulled the old metal fuel pump off and for some reason it dosnt have a rod on it that actually pumps so i put on from my k301 to see what would happen and now i cant even get gas out of the pump any ideas :bow-blue: is the pump on a k301 diffrent from a pump on a k181?

Yes, they are different - the 181 has a "straight" lever, the 301 has a bend in the lever. No rod? - does it have lever? could be vacuum actuated ....

Earlier K181s frequently came with pulse style (no lever) pumps

Did you ever get your belt problem resolved before moving on to this problem?

yes i did but this has been happening before i even put the 6 speed in but i just kept “cleaning the carb” but it always seemed clean but now it is worse and it will run after sitting for ever on idle but once you run it high it will run for maybe a minute then die

What about the problem you had with it not climbing? Did the pulley fix it?

well there was a couple things i changed the pulley that helped a little but i put a heavier reurn spring and i unhooked the clutch/brake rod and turned it in one turn and it really helped

Yes but it has to be a pump for a K181  Big blocks use different levers.

It may just be a $10 diaphragm that is your problem. Buckrancher sells them. I've changed a couple over the years. Not hard to do.

Have you pulled the fuel line that comes from the pump to the carb? Crank the engine, do you get a good pulse of fuel? If not the diaphragm might be it. Are you getting any fuel in the crankcase? That's a sign of a leaking diaphragm.
