these are directions for 2 cylinder, 2 carbed motors, but the principle follows for most other carbs.

Cleaning Carburetors First i ask you to follow the directions in your OEM Manual.

1. you will need a rebuild kit for each carb.

2. remove carbs trying not to disturb linkage adjustment.

3. dismantle carb, and place in carb clean solution, soak over night. ( do not put plastic parts in solution.

4. remove and clean the orifices (jets) high speed is usually behind the bowl drain plug, the slow usually top center of carb body, you will need special tool # 317002 to remove the orifices, or make your own. pictures below.

5 using compressed air. Blow out all orifices, with a small wire ( 2 or 3 stands of wire from an old extension cord) make sure all the jets are clear.

6. reassemble the carb body, with the carb up side dowm set the float parallel to the carb body.

7. complete reassembly,

8. take a clean piece of hose, connect to the fuel inlet, with the carb in operating position, blow into the hose, it should blow air out of the carb. now turn the carb upside
down, blow into hose, there should be no air allow thru. this means the float needle is seating, and stopping the flow, as it should.

9. reinstall, connect the linkage, and give it a try.

edit: the low speed is red arrow, the high speed is behind the bowl drain screw blue arrow.

Well done Tash.

Perhaps mention is item #6 that the carb should be flipped upside down when ensuring that the float is parallel and slightly off the face of the carb body. Realize this fact is known but perhaps someone attempting it for the first time may not know??

good point, thanks.

when i install floats, turn the carb up side down, now adjust the carb, so that there is just a little more space on the loose side, than the hinged side. this asures the needle closes. did you replace all the gaskets, tighten all the screws. now that the carb is together, attach a piece of hose the the carb, and blow into it. right side up, no air should pass, upside down you should be able to blow fairly easily. this shows that the float needle is sealing.

here is another with lots of pictures, but he did not get the high speed jet.
