well I thought I had this fixed but it returns. I have a Kohler K301 spec 47642d, last fall this motor would act like it runs out of fuel when it gets hot, I switched out the fuel filter, fuel pump and even changed the carb off a "no problem" k301 in another tractor with a bad BGB. thing seemed fine all winter, no problems. I figured I had fixed the problem. took the snow plow off tonight put the mower on it made 3 laps around the yards, same thing as last fall

anyone ever run into this before?

I had a kohler powered mower that run great until it got warmed up and would act like it was starving for fuel, pop, and die. Let it cool off and it would run like a champ until it warmed up again. The wire going out of the points box was partially in two. Replaced the wire and it worked great, problem solved. I would have to look at it to tell you where that wire went. My rememberer isn't what it used to be.

What about the head gasket ? The service manual recommend replacing every 5 years.

This sounds to be ignition related to me.  I would start there and then follow down the path of the head gasket idea.

 

Replace your condenser if you haven't already done that.

I'll second the coil. Happened to me a couple years ago with my 125 cub cadet with a k301 in it.

Sticking exhaust valve only when hot, My MF 14 did about the same thing as yours. Drove me crazy trying to figure it out. I put some transmission fluid in with the oil, that seemed to fix it.  Noel

What tractor are you working on?

 

I wonder if it is a tractor problem not an engine problem.

Allis Chalmers 712H. I am to the point of sidelining it and pulling the motor and slap a rebuild kit in it.

what is "BGB"?   and I don't think it needs a whole rebuild solely based on what info I see listed here, anyway
