| I bought a small gas chainsaw at a garage sale this weekend. I put a new chain on it as it didn't have one. It starts fine, it just won't cut. I have the blade on correctly as per the instructions. It just spins and will hardly cut at all. Could this be tension related? Bad chain? Any help is appreciated. |

Check the centrifical clutch. It may be frozen up and not fully engauging so it's not transfering the power from the engine to the chain. The Centrifugal Clutch The centrifugal clutch is the link between the engine and the chain. The clutch's purpose is to disengage when the engine is idling so that the chain does not move. When the engine speeds up (because the operator has pulled the throttle trigger to begin cutting), the clutch engages so that the chain can cut. You can see the clutch in the following photo: The clutch consists of three parts: * An outer drum that turns freely - This drum includes a sprocket that engages the chain. When the drum turns, the chain turns. * A center shaft attached directly to the engine's crankshaft - If the engine is turning, so is the shaft. * A pair of cylindrical clutch weights attached to the center shaft, along with a spring that keeps them retracted against the shaft The center shaft and weights spin as one. If they are spinning slowly enough, the weights are held against the shaft by the spring. If the engine spins fast enough, however, the centrifugal force on the weights overcomes the force being applied by the spring, and the weights are slung outward. They come in contact with the inside of the drum and the drum starts to spin. The drum, weights and center shaft become a single spinning unit because of the friction between the weights and the drum. Once the drum starts turning, so does the chain. |

Hi,I use a saw for a living . #1 Home depot sells a type of chan that is S**T! It must have something to do with a past lawsuit. Thay will not cut crap! Get your money back. #2 go to ACE or someplace else to get a chain. try again. What knid of saw is it? Oh, BE SAFE! |
Thanks bud, I checked the clutch and drum,both are fine. Looks like this saw was barely used. I think it is the pos chain. The saw is a homelite ranger 33cc. gotta go find a better chain. |
+1 Crepot Depot sells shit. Go to a Kubota dealership and buy an Ecco chain saw blade or at the very least get the ones that are sold at Lowes. |
16S, just got my first saw ...husky 350...any recommendations on arboring sites, good info on tree dropping etc? thanks ps..sorry for the hijack |
Cool I didn't know kubota sold chains. I can ride my 4 wheeler about a mile thru the woods and hit the kubota dealerships back yard

Raven, Husky is the best. As far as tress go I dont do tree work .I build retainig walls and steps with 6x6 timbers. I start and stop a saw about 100+a day. Husky is the way to go. You can get chains on line WAY cheaper than store prices. I dont have any sites saved but you can find them easy on line. |
thanks for the help anyway. I'm real happy with the saw so far... |
Homelite? I think we found the problem. [cough] Stihl! [/cough] |
Hey it was $5 bucks!! My wife says if I don't cut my damn leg off I can have a bigger one later
