Dissembling the clutch uses special tools to prevent damage to other parts. A trusted shop would be able to do this cheap, then you can reassemble without special tools

SOURCE: Squeeze throttle engine doesn't increase/tines don't turn

Most likely the throttle shaft on your carb is stuck from residual fuel. Follow your throttle cable down to your carburetor and see if the shaft is moving when you press the trigger on the handle. If not, try moving it by hand and see if it loosens up. If not you may have to take off the air filter cover and spray some carb cleaner in the throat of the carb while moving the shaft back and forth until it loosens up. That should work for you.

SOURCE: Engine runs fine on 2-cycle Mantis tiller, but

Your problem is a common one on Mantis tillers. The engine sounds like it is not breathing properly. I have fixed dozens of these problems and it is almost always the spark arrestor clogged up. The spark arrestor is found inside a small housing on the muffler (easy to fix). There are 3 screws that need to be removed to get the muffler cover off, then you will see a small housing a little over an inch long with another 3 screws...remove them and you will see a small screen that is probably clogged. Clean it and the housing with a solvent (I usually use carb cleaner) then re-install the arrestor and reassemble the muffler cover. This will fix your problem about 80% of the time.

If that is not the problem you may need to fix the carburetor (take my advice and just buy a new one...not much more expensive than the repair kit and a lot simpler.

SOURCE: Mantis 2 cycle - tines lose power.

I had this problem today. Loosen the flange bolt. Pull the engine off and check that the hex end of the shaft is lining up with the clutch pad in the engine-that it seats properly. Then make sure the shaft is seated all the way into the worm gear and put the engine back on. You will probably have to wiggle the shaft until it seats into the clutch. Tighten the flange bolt when the engine is seated flush with the worm housing (with no gap). That's all I did and the power is back up. Hopefully you still have your manual with the parts blow-up. (page 29?) BTW, have you checked that the wormgear is greased?

If the motor rpms up without drag it might be a bad gear in the transfer case or a broken cable if it's a cable drive, could also be a bad or stuck clutch. Hope this helps

Engine runs tines dont


The following was extracted from the Mantis owners manual..

At some point, you may find that the tines won't turn when you press the throttle. This may mean the engine isn't sitting all the way down on the worm gear housing. Perhaps you've been using your Tiller
for several years. Or perhaps you've removed the engine for use with the Mantis hedge trimmer attachment, then replaced it. In either case, the flange bolt may have come loose and lifted the engine up.
If this happened you'll notice a gap between the bottom of the engine clutch case and the top of the worm gear housing.

To fix this, loosen the flange bolt. Take the engine off the worm gear housing. Notice the hex head on top of the drive shaft . Inside the clutch case, you'll find the clutch drum. Make sure the hex head
lines up with the clutch drum inside the clutch case. Then put the engine back on the worm gear housing. Make sure the plastic carrying handle is not under the fuel tank. If you've followed these steps properly, there will be no gap between the clutch case and the worm gear housing. Make sure you tighten the flange bolt.

When I Start Mantis Tilleer it starts in gear ( tines are turning)


The Mantis has a speed controlled automatic clutch.

Lower the idle speed by turning the idle screw counter clockwise. The idle screw is attached where the throttle cable meet the carb. The screw has a pointed end that resembles a pencil point.

The engine speed should be adjusted just above stalling.

If the tines turn even when the engine pull rope is pulled, the the clutch is defective and needs repairing.

Honda FG100 Tiller - Tines wont move


I took the transmission apart and the gears were fine. The friction pads on the centrifugal clutch don't seem to make full contact with the drum. Does anyone know what the thickness of the friction pads are suppose to be? I used some belt dressing on the pads and got some movement on the tines. With no wear on the gears, I guess I'll be replacing the clutch.

Won't stay running...


I had the same problem with my mantis. It would start fine after a few pulls, but had no power. I changed the plug, replaced the carb completely...nothing helped. Took it to a shop and paid $70 for a tune up that didn't help at all, and the shop owner just said "sorry".
After everything else was done, I pulled the cover off the muffler, (3 screws) then removed 3 screws over a small spark arrestor screen and found it was clogged...cleaned it and guess what...IT WORKS FINE NOW!

The best and easiest fix I have ever done to a small engine. I felt like an idiot, because the exhaust side of the motor MUST be clear to work properly on small engines. The only reason I was removing the muffler in the first place was to check the compression and VOILA!!!

An easy and quick fix I recommend for all Mantis tillers before you waste money on carb issues (which is what the company will tell you to fix to solve this problem).

Craftsman rototiller 3 5 model 917 299130 leaks


Sounds like you are speaking of the float bowl.
It should not have a hole in it.
You could purchase the part from Sears or a small engine shop.
If it were mine, I'd remove the bowl, clean it, and patch with a gasoline impervious material such as JB weld.
