Thank You. I really think the pre-filter is bad but I thought I would blow the line and draw tube out while I had it apart to change the filter. It only stalls on occassion and usually when the mower is leaning to the right but it is beginning to happen more often. I feel pretty confident it is fuel related. I have changed the regular filter and cleaned the bowl and that didn't fix it.
I filled up with diesel late last summer and got in a hurry and left the cap off the tank.:confused2: I probably mowed 15 minutes or so before I noticed. It was hot and dry so there was a lot of chaff blowing around. I'm surprised it has gone this long without a problem. Thanks again.
