I use a socket in a driver to remove the valve seat and main jet housing. You might have to use a ratchet if they're too tight. The problem trying to use a box-end wrench here is, the thickness of the wrench...don't use a tool that comes in contact with the float pin posts. That's a real bad idea. The post might be damaged. |

Removing the valve seat.
(Photo Below Left) You need to use the right sized screw drive to keep from tearing up the jets. When removing the main jet (screwdriver at right) place an 8mm box-end wrench on the jet housing and unscrew the main jet. Then you can unscrew the main Jet Aerator (or main jet holder) with 8mm socket as shown in the photo below right.
(Above left) Unscrew the idle jet with a slightly smaller screwdriver. I really doesn't matter which order you do this in, but I recommend unscrewing the main jet from its holder/aerator, while it's still in the carb just because it's easier to hold on to.
Do I really need to say, "Organize the corresponding parts."
