20 Most Recent Hitachi CS33EB16 16" Rear Handle Chain Saw Questions & Answers

The oil pipe is poorly fitted to the oil pump and allows bar/chain oil to sneak past the seal. Buying a new oil pipe may not fix the issue since this is common on brand-new saws. Warranty work probably won't help you. How I fixed my saw: I bought two small O-rings about the diameter of the oil pump and fitted them to act as hose clamps around the oil pipe. See attached picture. It worked perfectly and now my saw runs out of fuel before oil. Sears/Craftsman have a great video on how to remove the clutch assembly.

hi just because you brought it 4 years ago does not mean it is four years old thats when you first used it the machine itself could be 6-7 years old anyhoo it sounds to me that when you stored your tool up last time may be for the winter there was still fuel left in the carburetor what happens is any fuel left in the carb will expand in cold weather and when it expands it stretches the diaphragm inside the carburetor hence as soon as you touch the throttle it will probably flood the engine making it hard to start i will need the full information on the make model engine size

I don't think that's likely to work out.

There are many possibilities. contaminated fuel, wrong fuel oil mixture. air leak in fuel line, carburetor contaminated, or needs adjustment, choke problems, throttle problems. Try a small engine mechanic.

Check the Hitachi web site where they will show you where to look.

No, and it's a potential fire/explosion hazard! You have probably lost the fiber or plastic liner that prevents this; it's a small disk that fits inside of the fuel cap. Purchase a new fuel cap for your machine ASAP!
