Remove the following parts from the carbs. See [[Carburetor photos]] if you're not sure where these are.

*Both pilot jets

*Both mixture screws ([[Removing idle mixture screw plugs|remove plugs]] first, if not already done)

*The springs for the mixture screws

*~~And the~~ small o-rings and metal washers.

The first thing you should do is look through those pilot jets that you removed~~, and make~~ sure you can see that the very small hole isn't plugged up. If carb cleaner ~~doesn't work~~, pull a single strand of '''COPPER''' wire from a piece of 14-18 gauge that you probably have laying around someplace, feed it through the pilot jet hole, and roll the jet around the wire.

Don't go overboard; you just want to remove the deposits from the brass, not remove the brass from the jet. ~~Usually letting~~ the jets soak in a powerful fuel system cleaner, like Chevron, will ~~do the job without need of the wire~~. The worse the deposits, the longer ~~it needs~~ to soak.

Don't go overboard; you just want to remove the deposits from the brass, not remove the brass from the jet. Letting the jets soak in a powerful fuel system cleaner, like Chevron, will help if they are really bad. The worse the deposits, the longer they need to soak.

Now, take the straw from the can of carb cleaner, press it into the port on the carb for the pilot circuit, and spray carb cleaner into the circuit. Carb cleaner should spray out of the port in the float bowl that you removed the pilot jet from.

When you have a good steady stream of carb cleaner coming out of ~~here~~, press your finger against the pilot jet port, and spray carb cleaner again into the circuit. This time, you should have carb cleaner spraying out of the mixture screw port, where you removed the mixture screw, the spring, the o-ring and the washer from.

Once you have cleaner coming out of the mixture screw, install the mixture screw and parts back into the port, and screw it all the way in until it just seats (don't crank it down). Now back it out 2 1/2 turns, make sure your finger is still covering the pilot jet port, and spray again. This time you should see cleaner coming out of the mixture screw port on the engine side of the carb at a tiny little hole.

Once the carb cleaner comes out of the mixture screw port you need to screw the mixture screw back in until seated, open up the throttle plates, and spray again. Right where the throttle plates lifted up away from are 4 small little holes. This time the carb cleaner will spray out of these holes.
