How do I find an owner's manual for Olympyk chain saws?


Check the compression on it. If under 120 psi it probably needs a rebuild. If it has good compression put a spoonful of fuel mix into the carb throat or sparkplug hole and try it. If it hits a few times the fuel system needs attention. Joe

Chainsaw won't start


Replace the condenser. You'll still get spark with a week or dead condenser, but no fire under compression.

My craftsman chain saw 18 will not start


The 3 things needed for an engine to run:
1. Compression (Cylinder, Piston, rings, gaskets)
2. Ignition (Spark plug, ignition module/coil)
3. Fuel (Fuel lines, Carburetor, gaskets, bad fuel)

More than Likely I would start by checking fuel related since that is usually the biggest offender (fuel lines broken/dry rotted, bad carb.)

61 fires up then dies,seems to be good spark and gettin fuel


If the saw has good compression and spark (check them with proper gauges) check the fuel lines and fuel filter. If this all checks out, then the issue is probably the carburetor itself.

Chain saw will not start


sure sounds like you did it all.
Was the Plug wet with gas when you took it out to fuel it directly? I would take the plug back out, blow out or let the Cylinder totally dry. Then spray a bit of Starter fluid in the carb and see if you get life.
Old gas left in a saw is a Carburetor killer. The paper components in these carbs can not stand the new 10% ethanol gas.

Mcculloch 3516 chain saw, does not always start.


It must have spark, fuel and compression to run. Your task is to figure out which is missing.
Sometimes electrical components quit operating once beyond a certain temperature. Does it always start cold and become tempermental when warm?
IMO most hard start problems on a chainsaw with a good fuel delivery system are flooded.
Start Procedure
Cold:
  1. Ignition on/off to on
  2. Set compression release – optional step even if saw is equipped with a compression release
  3. Pull (close) choke, set fast idle (done when choke closed on some saws); pull starter and listen for an attempt to start. once heard (usually two pulls; no more than 4)
  4. Set compression release – optional step even if saw is equipped with a compression release
  5. Push (open) choke pull starter until it starts. (usually first pull)
Warm:
  1. Ignition on/off to on
  2. Set compression release – optional step even if saw is equipped with a compression release
  3. Pull (close) choke, set fast idle (done when choke closed on some saws) - Don’t pull with choke closed.
  4. Push (open) choke, pull starter until it starts. (usually first pull)
The 3516 is a MTD McCulloch (Chinese). These saws are in a class by themselves. Good Luck

Describe your Husqvarna "Chain Saw -


Remove the spark plug and test for spark. If ok, try some starting fluid in the plug hole, install the plug, and try to start. If it runs a short time, it is not getting fuel. Check fuel lines including inside the tank. Clean or replace the air filter. If this saw is fairly old, the carburetor probably needs a re-kit and cleaning. Does it have good compression? Check the muffler for plugging. Make sure the fuel/oil mix is fresh. Good luck!

Saw will not start Husqvarna 350


Hi

An engine needs three things to run(fuel and air mixed together in the correct proportions,compresion of the fuel/air mixture and ignition).Make carb adjustments,check the compression and the spark from the sparkplug.Priming the engine(put some gas into the sparkplug hole).Try to start the engine.If engine is running only the gas from the cilinder,the chain saw has a fuel delivery problem.Disassembly the carb and clean the inner parts.Check the fuel and air filters,fuel hose and gas tank ventil.

good luck!savumihai71
