If it’s old then its got points ! they need to be cleaned or replaced if condenser is old as well then it needs to be replaced , replace spark plug or clean it well in solvent to it shines again! inspect the bar /chain/sprocket for shiney spots (wear) last but not least clean/replace air filter
if it’s got an auto oiler then make sure the filter and pump work on that as well

if it’s got a in tank gas filter then replace that as well and ck priming bulb for any cracks

How to Identify and Fix Common Gardening Problems ?

We provide a variety of viewpoints on how to identify and fix common gardening problems. Our sources include academic articles, blog posts, and personal essays from experienced gardeners :

Adjust the low-speed adjustment screw on the left and high-speed adjustment screw on the right with a screwdriver. Turn the low-speed screw clockwise until you feel the needle touch the seat. Turn the low-speed screw back counterclockwise one and one-third turns.
The letters on the screws represent High (H), Low (L) and Idle (T). The H screw regulates the Air/Fuel mix during high RPMs, while the L Screw does the same during low RPMs. The T screw regulates how much fuel is sent to the carburettor while idling until the throttle is pressed.
Locate the idle mixture screw and turn it clockwise until the needle lightly touches the seat. Then, turn the screw counterclockwise 1-1/2 turns. If your carburettor has a main jet adjustment screw at the base of the float bowl, turn the screw clockwise until you feel it just touch the seat inside the emulsion tube.
The first is the pitch, or the distance between drive lugs on the chain and it determines whether the chain will fit the sprocket. Most saws use 0.325″, 3/8″, or 0.404″ pitch, with 1/4″ less common. Most consumer saws use a type of 3/8″ chain called “low profile”.
The sharpening angle will generally be between 25° and 35° – the harder the wood, the greater the angle. To maintain the correct angle, we recommend that you use a sharpening grid or a filing gauge as an aid.
If the mixture is too lean, it will leave no color, while a rich mixture will cause the fuel ring to become more prominent. Over-rich mixtures will give the plug a sooty appearance.
Find the adjustment screws on the front of the carburetor.

There should be two screws on the front of the carburetor, which are used to adjust the air and fuel mixture. These often look like flat-head screws, and you can use a screwdriver to turn them, adjusting the amount of fuel and air mixing in the carb.

Set idle speed adjusting screw, clockwise to increase rpm, counter-clockwise to decrease rpm. Idle rpm range should be 950 to 1050 rpms. Adjust idle mixture by turning idle mixture screw slowly clockwise until the engine runs poorly.
Most modern chainsaws, string trimmers, leaf blowers and other small-engine two-stroke equipment recommend a 50:1 oil mix ratio, but some recommend 40:1 and older two-stroke equipment might even call for 32:1.
325 is a smaller top cutter and tie strap it is easier to turn for a saw . The 3/8 is a bigger top cutter and tie strap .
The fuel line may be clogged from stale fuel deposits, more reasons to cause your chainsaw to cut out when applying throttle. If a fuel line is cracked, it will leak gasoline and draw air from outside into the fuel line. If the line is leaking fuel, it needs to be replaced.
Always hold the file at a right angle (90°) to the guide bar. The file only sharpens on the forward stroke – lift the file off the cutter on the backstroke. Rotate the file a little at regular intervals while filing to avoid one-sided wear.

I was using the saw as a chain saw last weekend to cut up an old tree stump when the chain came off. I don’t know how to access it to put it back on and don’t have a user manual. The saw belonged to my late father and I don’t know if he even kept the manual.
ANSWER : You will have to remove the cover on the side the chain bar goes into. There should be one or two nuts holding the cover on the side. The is also a chain tension adjuster you may have to loosen to put it back on. Make note of the direction of the teeth on the chain. It is an directional chain. The tension adjuster is usually a flat head screw on the front side right beside the chain bar.Unless it is a really old saw, manuals are available from most manufacturers for free download. See if you can locate a brand name and model number.

Chain saw chain is loose
ANSWER : Loosen the side cover nuts, then turn the adjuster CW to bring the chain up to the lower edge of the bar, then check to see if the chain will move fairly easily by hand. Tighten the clamp nuts and recheck tension. If chain seems to get loose quickly again, it may not be sharpened correctly causing heat to build in the chain. You should see no reflection of light from the cutting edges if filed correctly and the saw should require very little pressure for it to cut rapidly. Hope this helps!

My 18 Inch chain saw will not keep oiling the Chain, I had it worked on and He said it was plugged. How do you unplug it with out taking it all apart. Is there a spot to blow air through. the Preacher..
ANSWER : Remove the chain bar and look just below the bolts holding it in place. You’ll see a small hole where the chain bar oil pump pushes out oil. Make sure this hole is clear then run the saw without the bar on.

Be CAREFUL of fingers!

You should see oil coming out of that hole. If not, you may need more serious work done with the saw (chain bar pump replacement).

Are chain saw chains interchangeable
ANSWER : Yes, but you have to have the same length/number of teeth, the same pitch and the same gauge chain as the original. If all those match against the original, you can use the chain, no matter what brand. Stick to a good chain brand though like Oregon or Carlton etc
