Question about Garden
This is a recent situation on my Honda lawn mower which is fitted with a 5.5 hp GXV160 engine.
Cleaning the air cleaner element helps this problem also

In either case. Here is how to clen the carb properly:
Before you start.... if you have a digital camera take "close up" PICTURES of the linkages and springs attaching to the carb. If this is your first time you will be so glad you did. You can always delete them later if you don't need them. :)
Here is what you need to do:
1. Fuel selector off
2. Remove float bowl mounting screws and nut
3. Remove the BRASS Jet / Orifice in the very bottom of the venturi tube inside the pickup tube. (Flat blade screwdriver) Hold the Orifice up to the light. You should see a pinhole. If it is not clear clean the orifice but do not force anything through the hole.
4. Underneath the Orifice there is yet another BRASS tube that you need to remove. (Flat blade screwdriver) Make sure all of the holes in the tube are clear. The tube will be over 2 inches long. Clean it and reinstall it.
5. Reinstall the Orifice.
6. Using a catch fuel container turn on the fuel selector. Fuel should flow at a good rate. GENTLY lift the float assy level and make sure fuel flow shuts off. When you drop the float again fuel should flow.
If you do not have fuel flow at this point the needle and seat will need to be inspected. Fuel selector OFF.
(The following procedure is to be done only if there is no fuel flow with fuel selector on.)
a. Remove the silver float pivot pin retaining screw
b. Drop the Float down (The needle will come off with the float. NOTE the position)
c. Inspect the tapered rubber of the needle If should be pointed. If it is not pointed then the rubber tip is stuck inside the seat.
d. Clean the seat hole ONLY if obstructed. (Easily damaged)
e. FUEL Selector on then off fuel should rapidly flow through the needle seat.
f. Renistall Float and needle making sure to get the pivot / hinge pin installed correctly and reinstall the silver retaining screw.
g. Fuel selector ON. Raise and lower float checking for free movement with fuel flow when lowered and stopped when the float is raised level.
NOTE if fuel does NOT stop when float is level you will need to bend the float tab (tab up if level is too high or tab down if level is too low) where the needle attaches to the float assy until it does.
7. If there still is no fuel flow at this point remove the fuel hose from the carb and check fuel flow. If no flow check that gas tank exit hole, fuel filter (if installed) and the selector valve assy for obstructions.
FUEL FLOW IS GOOD
Step 8 is VERY important"
8. BEFORE you install the float bowl inspect the bowl nut. There are 2 holes in the side of the nut where it screws in to the bottom of the carb that must be clear.
9. Install Float bowl mounting screws and nut. Check for leaks.
10. Test engine.
If it is still hunting gently grasp the carb and try to move it up or down. Your checking for loose mounting bolts. If it is loose tighten the 2 mounting bolts.
That should do it.
If the engine STILL hunts after all of the above there is still more I can pass on to correct the situation. We just need to communicate by you letting me know that you still have the engine hunting problem.
Thanks for using FixYa.
