My 644 gave up the ghost

The muffler was shot on my 644 when I purchased it. I liked this on that Steve Guider made up and purchased one.

This engine is so powerful that by the sheer strength of its exhaust blow it broke the weld and spit out the muffler on the ground.

thank you for the recommendation @Harry

I actually like the muffler routed to pass all the gases below and to the back of the tractor, so I'll just weld it back into place.

Not a pretty weld but should hold. A little stove paint for good measure. On to the next adventure.

My 644 just hasn't been running thats well lately. Today I needed to do some work with it after sitting for about a week and a half but it just wouldn't start. Replaced the carb with one I knew was good, still nothing. Something made me have a look at the fuel pump. When it came off I noticed one of the two bolts that fastens it to the blocked was loose. Inspected the fuel pump, seemed to be fine. Put it back, added some fresh had and to my surprise the tractor starts much faster and the motorboating is gone completely. This Kohler K321 runs now nice and smooth, better than ever before since I got the tractor. Even got some seat time hauling some skid from here to there.

I love an easy fix! So since the fuel pump was loose, it wasn’t pumping as it should? Or do you think you cleared out some junk in the line?

Mind you it took me about 40 minutes trying two other carbs before getting to the fuel pump, but definitely it was an easy fix. Not sure, maybe some junk made it to the carb before I installed the fuel filter a little while ago. Let's hope it stays running well now as I need it for some work.
