CUB CADET 1000

I checked ring gap, they in spec spacing. It is not stopping, it just looses power all of a sudden. The last time it ran about 15 mins. then started loosing power. Not like running out of gas. Not cutting out. I am cutting grass checking it out. I have a 108 with the same engine, I rebuilt maybe 10-15 years ago still running (starting to smoke a little), I bought this one new in 1974. The 1000 I bought used not running.

From the sound of it, the tank may have a blockage starting at the fuel nipple or the fuel filter is choking up. Gradual loss of power is fuel issues.

That will also contribute to the heating up, because the fuel mix is getting too lean. A rich mixture will not cause an overheat.

Verify the fuel lines do not have anything in them like a dirt-dobber (bee) nest. I have had to blow through all of my fuel lines, both new and old before if they were left open even overnight.

Checked fuel lines. All open. I run an inline fuel filter (clear) so you can see what is going on.
