my power king wont run after it starts and runs about 15 to 20 minutes.It will start stalling and i can pull the choke out and it will sommetimes get me 10 more minutes of running.it wont start till it cools all the way down.It done this when i first got it,I put a new set of points and readjusted the valve lash,rebuilt the carbrerator,it fixed it for the summer then it started up again.The carb is wore out,it was almost past rebuilding.Someone told me it could be the valve stem guide thats letting the valve losing up as it run and gets to hot.Does that make any sense.some one help me this is the one i use the most and one of my favorite tractors too.Rick Smith

Sounds like it's possibly vapor locking? Either that or gunk in the carb. Usually 15 minutes wouldn't be long enough to get it hot enough to vapor, but possible. Try rerouting the fuel line, make sure the fuel filter is clean & try it again.

Also, check the vent on the gas cap. It could be causing a vacuum in the tank if not venting properly.

I would try some GumOut or Seafoam in the tank & mix it heavy (2x directions). If the Additive helps, continue to use it every tank, just mix it as per the directions.

Welcome to GTalk , it almost sounds like it's running out of fuel , did you try opening the gas cap in case the vent was plugged ? I'm sure others with have more ideas for you , Al

First, welcome to the site! It sounds like something is backed up. I would clean the carb, replace any filters and make sure all the lines are clear. I had the same exact problem with my '71 1614. It turned out to be gunk in the petcock, restricting flow. We would love to see pics!

It does not have to look like showroom new, although a good paint job is always nice! I would rather have an ugly tractor that is a real workhorse then have a great looking tractor that can't do anything.

We would love to see some pics of the MF14! Make sure to post them over in the Massey section!
