Dies in 20 minutes CC30 H

[Yorston Bill]

I bought a used Cub Cadet CC30H, it starts and runs well for about 20 minutes, then it misfires and dies. I have fresh fuel, new fuel & air filter, new spark plug and oil/filter change.
After about 10 minutes it starts and does the same again. I don't hear a hiss after it dies and I loosen the fuel cap so doubt that's plugged. When I replaced the fuel filter I did install a paper element filter vs a red screen type, could that be a cause.

Is it a gravity fed fuel tank? Does it have a fuel pump? Did it have a red fuel filter on it initially?

How did it run before you changed those parts? If it is a 10 Micron filter it can cause the engine to starve for fuel since the engine does not have a fuel pump.

Tks for the reply, unfortunately I bought it at an auction, did the cleanup & tune up routine first, then noticed the issue with first use. I'll pick up a little red one and switch out the filter.

Tks for the reply, yes it had a red filter which I replaced, I don't think it has a fuel pump, hose from tank to carb.

Next time it happens check for spark. No spark means you have a coil which either opens or shorts when it gets hot. Time to replace coil.

According to the IPL this engine came the 70 micron White pancake filter per the PN. Now the Red pancake is a 150 micron filter. Many paper type are in the 25-30 micron range. Depending if the tank bottom is above the engine's top then these 25 micron filter usually still wok fine. I run a Briggs 33 series that is gravity fed without any problems using a 27 micron filter.

She how she runs with a straight raw fuel line off the tank. Or auxiliary fuel tank.

Do a visual inspection on the inside of the gas tank and make sure you don't have some debris that is floating around and then plugging the inlet hole (not making it to the filter). Floating again, and replugging.

Tks for the reply, maybe not the problem
