I have had the same problem.
The first time the solution was to replace the rubber membrane underneath the primer bulb. Take off the bulb, then remove the plastic part underneath the bulb. There is a rubber membrane underneath that. The ethanol in the gasoline tends to deteriorate the membrane. The honda dealers sell them for about 14 dollars.

The second time the problem was caused by the gas cap, not properly venting. In this case the engine would start and run, but when I gave it full throttle, it would quit.
It got so bad that it wouldn't even run. I noticed when I loosened the gas cap it ran great.
So I took off the cap, removed the inner parts, and got a diaper in and pushed it though the holes in the plastic part underneath the cap, and through the rubber plug in the center. I did this a few times and check with my mouth to see if I could pull some air through the cap. When it breathed satisfactorily, I put the cap back on the gas tank and it ran great. Now it runs better than new.

Is this a 2 stroke (or 2 cycle) engine requiring premix gas & oil? if so, is it mixed at the correct mixture? if only gas (no oil) was used, the piston will not have the lubrication required in the cylinder to keep it running.

also, after the tiller is warmed up, are you opening the choke? it will not run long with the choke on and warmed up. turn the choke off after a few minutes, then begin tilling.

hope this helped.

Honda FG garden tiller 110, stoped running, took it apart, the timing belt loose, what do I need to fix it? Or is it worth fixing?


I'm not aware of them having a timing belt. Do you mean the drive belt? if so, it is supposed to be loose. in the disengaged position. and tight in the engaged position. and to answer your question it is almost always worth fixing. unless you have a lot of money and want a new one. I've seen tillers 30 and 40 years old work just as good as a new one.

Just purchased a new FG 110 tiller it seems to run fine for a while then I have to release the throttle to keep it from stalling out. It has less then 20 minutes of use. I have installed the oil. It will...


It sounds like you may have a "lean" carburetor mixture setting on the high side or full throttle. This carburetor may have limiters or special screws that will make it difficult for you to adjust. You may try contacting a dealer to see if they could try adjusting it for you or just take the unit back.

Honda mini tiller cuts off when start tilling. runs great when held above ground with no load. cut off seems to be associated with the movement and shacking when tilling ground.


Hi thermo259, sounds like the high speed adjustment is lean, find the high speed screw and turn it counter clockwise 1 half turn and see if that helps. Should cure it.

While operating the Honda FG-100 mini tiller, the tiller suddenly stopped turning. The engine runs fine. I couldn't find any advice in the manual. Any help would be greatly appreciated.


If the tines become jamed, the tiller will stop. This is especially true if you are preparing your lawn for seedng without doing an preparation of the ground. Also, check you accerleration line, there may be a loose connecton.. Otherwise, sounds like a service issue.

Tines rotate slow when I try to till.


The clutch is non adjustable if the clutch fails you will have drive all the time or it slips. if the tines spin at the same speed with the engine at low and high speed the clutch might be slipping, the common cause for this is the gear box is partly siezed due to no grease being pumped into it, most ppl dont even know about this untill its too late. you have to remove the LH side tines to get to the screw.

I have a Honda mini tiller FG-100. Haven't used


You need to check your engine oil on a very level surface.

Its all too easy to over fill these engines with oil and the results can spell disaster if not rectified. On a level surface, with the machine level (not tipped forward) the oil should just be reaching the top of the threads for the bung. Any more than that and you have to much in.

This symptom can also be caused of incorrect storage .ie the machine being left on its side allowing oil to fill the exhaust box.

Check your oil level first then run the machine until the left over oil in the exhaust box has been burnt off. I would then advise either replacing the spark plug with a new one or cleaning your existing one and checking / replacing your air filter
