Question Fuel Solenoid Piston

Should I be able to remove the piston from a fuel solenoid body? The piston moves up and down, and operates with the key. But, if I try to lift it completely out, is seems to get caught on something. It was completely frozen, but I used carb cleaner and got it moving. Does it need more cleaning?

This is on a Craftsman 13.5 HP riding mower. The part number is 699915.

No, it doesn't come out. If it moves up and down with voltage, then it's good.

If it's working then I'd go with it like Cheese recommended. It's a common back yard "hack" to pull the piston out and cut it off. The engine will run but you may get backfiring when you turn it off so it's best to keep the anti back/afterfire solenoid working if you can. Here is the Briggs page that discusses it.
