Question about Honda Garden
HI the mower adjusting screws have been adjusted & ineed to reset any ideas ?
Before you remove or try to adjust your low and high speed jets you should always count the number of turns it takes to lightly seat the idle mixture screw and high speed needle adjusting screws.
Be sure to write the number of turns down on a piece of paper so you will know how many turns from the seated position to open the jets when you go to reinstall them, or if you remove them for cleaning or replacement.
If you have aready tried to adjust them then the adjustments below should get it running for you for final adjustment when warm.
Normally you will adjust your idle jet to 1/2-3/4 turn open from the bottom seated position.
Then you will re-adjust the low speed of the engine when the engine is warm by turning the idle screw in or out till the engine runs smoothly at idle speed, around 1200 RPM.
The high speed jet is adjusted to 1 1/2- 1 3/4 open from the bottom seated position, after the engine is warm.
Then re-adjusted by turning the High Speed jet adjustment screw in or out till the motor runs smoothly at high speed.
Alway use the "lightly seated" method if you have not changed the screw settings.
Please take time to rate me

SOURCE: mixture adjustment honda hru 173
Hi this most honda engines dont have a mixture adjustment screw they only have a air bleed adjusment on the front of the carby close to the head though you can only move it a bit either way on some others should be about 2 turns out from closed, the main problem that honda engines have is they will still run with water in the carby , I would try cleaning out the carby bowl first its only held on with a bolt in the centre.

Take the covers off the drive,there should be a hollow bolt the cable comes thru, it should have 2 adjustment nuts This lengthens or shorts the cable. There also may be a adjustment on the handle.

Hi and welcome to FixYa. I am Kelly.
Have you removed the air cleaner and briefly tested the engine to see if the problem persists? Air cleaner is usually on the left front corner of the engine as you stand behind the mower. A dirty air cleaner will cause the exact same symptom you describe. A sticking or not disengaging choke will also cause the symtom you described.
Ok having said all of that.... Your carb item 34 this link: http://www.lawnmowerpros.com/Honda/Honda-GXV160-Engine-Parts-Diagram.asp
can be cleaned by you.
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.
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
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.
That should do it. (carb cleaning 101)
Thanks for using FixYa.
