This chart is intended to be a helpful guide when troubleshooting your carburetor. Each incident varies in accordance to individual use. Regular inspection of carburetor parts is recommended. Always consult your owner’s manual for specific Carburetor tuning and recommendations.
PROBLEM POSSIBLE SOLUTION. Engine hunts (at idle or high speed). Carburetor Leaks Examine idle and main mixture adjustment screws and O-Rings for cracks and damage. Sounds like the needle is not seating and/or the float needs replacement. Most of the floats in small engines do not have a metal tang to adjust them with unlike snowmobile’s, motorcycles, and outboard boat motors.
You will have to take the carb off and dis-assemble it to verify. The other thing that could be happening is you are using too cold of a spark plug. To cold of a plug does not ignite all the fuel in the combustion area. If you use too hot of a plug it will overheat and cause detotonation and pre-ignition. Just a few things to look. Please help, I bought a brand new wood splitter last fall on clearance with a 6.5 Koehler.
It sat in my shed until this summer when I pulled it out put it together and put all fluids in and tried to start it. Only premium gas and I pull and pull and pull and it will kinda Pop off and won’t want to go. I’ll choke or no choke or no throttle or 1/2 or full with all positions of the choke and nothing. Took carb off to clean junk out of it. It was perfectly clean, still pulled all jets and screws out cleaned With air gun. Same thing when got it back on.
If I dump a little gas down the carb a couple times, I can finally get it to go. After it starts, runs perfect and not a single problem. When it is warm and shut off, it will start right back up. Only cold starts the thing is a pain in the butt.
Any input would be great. It’s just frustrating being brand new and thing won’t start when you want it to. Thanks Billy. After rebuild my fz16 motorcycle engine, I,m facing a painfull problem, when I start my bike or riding, my rpm gose down for a moment and came back again, its like starving for fuel.
But my tank is full. Usually it appears frequently between 2 to 3.5k when I throttle or goes to change the gear. Then again I checked the carburetor by keep the bike in “N” in gear and throttling, I saw, its like my carb is blowing wind, its give a slight sound like “BOOt”when the rpm goes down and vibrates. Its happenig frequently, some times engines also dies.
Pls some one help me. I took the bike to several machanics, no 1 giving me the solution, i also changed a orginal new carb but no solution. I have a Honda GCV160e lawn mower engine on a Husqvarna flymo.
It started last year to leak fuel through the air filter. I cleaned the carb and looked at the float and float pin for wear etc and it all looked goodno leaks in the float. It persistently carried on leaking fuel. Sometimes it would be after twenty minutes and sometimes it would be longer. I have manged to run it for two hours without any problems whatsoever. I bought a new carb and fitted it and it ran beautifully until the next time I came to use it and I couldn’t start it. I took it in and I was told that the float had stuck.
It worked but when I refilled with fuel I had trouble starting it but it did eventually start. This season I started my lawn mower on the second pull and it cut beautifully. I stopped it and then moved it round to the front having turned the petrol off in transit.
Turned the petrol on and it started. It ran for about five minutes and then fuel came through the air filter again. I asked a garage for advice and I asked if it could be a sticking valve that is causing the problem and they assured me that it was a fuel problem and to clean the fuel tank. I have done this having taken the whole thing off the machine. It did have debris in the tank. And to my surprise dead grass. I cleaned it and let it dry and put it back on the machine.
I have just started it having put the old carb on and again because I thought maybe it is the fuel tank, fuel immediately oozed out of the filter. Could a sticking choke cause a problem?
Is it still a fuel problem? Is it a sticking valve? I have spent a fortune taking it in and as soon as they get it started they think that it is ok, but it clearly isn’t. It is a 12 year old machine that basically does 2 hours of mowing at the beginning of the season virtually every week and then down to possible every two week come June. I was told by the guy who gave me advice over the phone that he has machines that are over 20 years old and are still running with the same engine and valves. Is it basically a case of the engine not processing the fuel properly?
It doesn’t excuse why I can run it for two hours sometimes. I am really fed up and I know I am a woman and don’t know much about engines but I have had the carb off more times than I care to mention. I am now going to put the new carb back on and see what happens but I am fast losing patience and I am surprised that when I have taken it in they haven’t looked at the possibility of the tank being contaminated. Any help would be appreciated!
Thank you so much from a very frustrated lady who is almost frightened to use it! I forgot to mention that the first time it leaked fuel the machine hydro locked and I had to free it.
Every time it happens there is fuel in the oil. I was told this was normal as fuel is backing up. I am thinking that it is a valve possibly sticking but again I don’t know enough about engines. New cub cadet ZTR with Kohler 24hp 7000 engine 3.5 hours Ran out of gas while mowing. Filled with gas. Unit will not start Suspected gas from can was possibly old (2 months) drained gas tank from fuel line on the fuel line down line of filter. (filter not plugged) Fresh gas.
Spark to both cylinders (in line test light) No start engine cranks but does not fire Checked output of fuel pump. Steady stream while engine cranks checked solenoid on bottom of carburetor. The pin retracts as it should when key turns. Took the bowl off, full of gas. Ensured the opening that the solenoid valve closes was not plugged. Will not start putting a tablespoon of gas in the throat of carburetor, engine starts immediately and runs 2-3 seconds until tablespoon of gas is consumed Fuel blockage somewhere????
I am at wits end, I’ve never had a problem like this in all my years of small engines. Can take the unit for warranty service but there is a 3 week backlog. May need to buy goats to take care of rapidly growing grass Thanks in advance!
Frustrated Ned. I’m having yet another carb issue that I could use help with. Subject- Honda string trimmer model #HHT-25S. I was convinced (by my brother) that a 4-cycle Honda was the ‘way to go’. Fast forward The latest issue.–having replaced the carb, the gas filter, the plastic ‘purge bulb’ and a new air filter it still (so do I) has issue. The purge bulbs does not stay filled with non-ethenol gas. It runs to empty and the engine dies.
I swear, prime the carb and repeat. It runs for a minuterepeat. New purge bulb looks good, and 2 hoses into carb look good.
Their clamps are on correctly. The filter at the end of the gas lineinside gas tank is new and looks clean. I just purchase a Pulsar NS200 before two week and I completed my first service before 4 days.but I feel some problem in my bike. I feel like the bike is running without fuel at 3500 rpm.(some missing)exactly at 52km/h at 3500 rpm.Am not getting much confidence to ride my Bike.after service they kept that two days with them.still there is no change.they are telling that they can’t identify the complaint.
Huayi Carburetor Manual Tuning
Please give me a replay for my mail.how can I over come this problem? Am waiting for your helpful reply. MY TROY BUILT TB90BC 41BD190C966 2 CYCLE HAS RUN GOOD FOR SEVERAL YEARS. THIS YEAR WHEN i STARTED IT IT WOULD HESITATE AND/OR STALL AFTER i MOVED THE CHOKE TO (3) OFF POSITION ONCE IT WAS WARMED UP.
OR IF i TRIED TO ACCELERATE THE THROTTLE IT WOULD HESITATE AND THEN STALL ON ACCELERATION; I REPLENISHED THE FUEL WITH 40 TO 1 RATIO; CLEANED AND THEN REGAPPED SPARK PLUG GAP. EXPERIENCED SAME PROBLEM; AS WELL AS IT ALSO DOESNT WANT TO RUN VERY WELL WHEN CUTTING STRINGS TURNED TO CUT VERTICALLY TO EDGE GRASS.
I NOTICED WALBRO CARB HI & LO SPEED SCREWS APPEAR TO HAVE A CAP OVER HI LO SCREWS TO ELIMINATE ABILITY TO ADJUST THEM LIKE IN PREVIOUS YEAR WALBRO CARBS. DO YOU IF SCREW CAPS ARE REMOVABLE TO ALLOW HI LO SPEED ADJUSTMENTS? OR ARE THE SPECIAL “D” SHAPED HI LO SCREWS SCREWS TO PREVENT ADJUSTMENTS? ANY SUGGESTIONS?? I have a two cylinder Briggs and Stratton build Craftsman ELS 725 22 HP engine on a riding lawn mower. I have been having trouble with it at highs speed/load with it misfiring, During the misfiring periods I will hear backfiring in the muffler indicating that there is fuel there but not ingniting.
It seem to be on one cylinder, but the intermittent nature of the problme hasn’t permitted me to identify which. Sometimes pulling and resetting the choke will clear the problem sometimes, not.
It has a two barrel carb and I am instinctively believing the problem is most likely there but I’m at a loss as to how to approach diagnosing or repairing the problem. Engine was tuned up earlier this year. I have a question about small engine fuel systems. We have bikes, and generators stored at the desert.
Huayi Carburetor Adjustment
Many times they will not start due to swollen or decomposed gaskets or o rings in fuel shutoff, and carburetors. The question is; If removing the ethanol from the fuel (mixing water with the gas, then shaking the container to have the water absorb the ethanol, then draining off only the gas) then adding a very thin 2 stroke oil to the fuel (maybe 100 to 1), will the oil leave a film on the inside of the gas tank, and rubber gaskets to somewhat protect the parts from rustetc.
