Honda lawnmower GXV 140

My Honda Mower is about 14 years old. It goes well but every now and then it seems to run rich & tries to die. It loses power & blows black smoke out of the exhaust & I have to push throttle flat out or sometimes on choke to keep it going. I've cleaned the carby out & checked fuel supply etc to no avail. It has done this from almost new & of course it never plyed up when I took it back under warranty. Can you help? Lou.

I have a similar Honda (with the overhead valves) that someone gave me because it didn't run at all. Turns out it had a stuck open exhaust valve. I got it unstuck and changed the oil. After running it about an hour, the valve stuck again. I think this is an inherent problem with these engines. I cleaned up the valves really well and lubricated them. Then I put a high quality synthetic (actually motorcycle racing) oil in it and have been running it for a year now with no problems. Not sure what your issue is, but with stuff blowing out of the exhaust and loss of power, I'd pull the valve cover off (prop up the front of the mower and you can do this without losing any oil). Check your valves and give them a good cleaning. They may not be seating properly, which would cause the symptoms you describe. I'm just an amateur, but I'm learning every day! Hope this helps and best of luck to you Lou.

How do I fix My Honda hrx217 surges at idle runs ok at load.h


The carburetor has two circuits, a main power circuit and an idle circuit. When the idle circuit gets partially clogged, the governor will drop the throttle shut, the engine partially dies and the governor yanks the throttle back open till the main kicks in. If the idle circuit gets completely clogged, the engine will need the choke partially on to make up for the missing air fuel mixture, will run rich and surge horribly. The carburetor needs to be cleaned out, a can of Berryman's spray can dissolve the crud out and restore operation. 90% of this problem is caused by old contaminated gas

GXV 160 Honda, spark plug very sooty, when pulling to start it fires back through carb, have reset valve clearances which were near good enough but wondered about timing or poorly seating valves


you need to do a cylinder leak down test. That will tell you if it is a valve, which one or if it is rings. Try a compression test too. 5 pulls should be 160 to 190 ish. If all that is ok check the carb to see why it is causing a rich running scenario

HOW DO I FIX THE OIL LEAK COMING FROM UNDER MY GXV 120 LAWN MOWER ENGINE?


Depends where it is leaking from, wash it off to see where it is coming from, it may well be the bottom crankcase seal, once the blade and carrier are removed you should gain acess to this, if it is leaking you will need to remove the seal and replace.

Honda HRM215 lawnmower won't start. I am looking


Check for spark. Pull the plug and look at it. Make sure it isnt oil or fuel fouled.

Check the airpath and make sure the filter isnt blocked.

Check the fuel. Make sure you have clean gas in the float bowl. You can drain the carb without taking it off the mower. The bottom of the bowl should have a drain bolt in it. Remove the bolt completely and fuel free flow for a 30 seconds to make sure you chase off any water or dirt that may be in the bowl.

You may want to check compression. This mower is 19 years old and may be losing compression to the point where it wont draw enough fuel to run. Look for at least 100-110 PSI. Anything less you should consider adjusting the valve clearances to see if that helps. If not you probably need a new mower. Since repairs like this are very expensive.

Fuel mixture appears to be too rich on myHonda lawnmower


There is an air/fuel ratio adjustment screw on the side of the carburetor. Turn this back and forth until the mower runs smootly.
