- Verify there is spark

- High/low needle intital settings: Turn in until they lightly touch the seats then turn them out 1-1/2 turns each.

- Check the choke slide to ensure it is engaging the coke linkage

- Proper starting procedure:
A - Slide the choke to the rear/on position.
B - Set the throttle to half throttle. (Squeeze the trigger & hold it while you push in the locking button on the side. Hold the locking button in while you release the trigger.)
C - If the saw hasn't been run recently, you can take the air filter off & pour a small amount of mixed fuel into the carburetor before trying to start it.

If it start but doesn't keep running or won't start back up, the vent may be plugged.  The vent is a short piece of hose with a set screw pushed 3-4 threads into it.  Do NOT screw it in.  If it is screwed in, the threads will cut into the tubing creating a seal which will prevent fuel from reaching the carburetor due to a vacuum.

These are fairly simple saws.  I have 2 - 08s & 2 - S10 top handles, basically the same saw which I use regularly.

Hope this helps.

You say when you put the filter on it won't run, but will otherwise? Is the filter new? Have you tried a different filter to make sure this one will allow fuel to flow? Also could be the metering lever set too high. With no resistance with the filter off it can pull fuel but the added resistance of the filter holds it back? Lever should be flush with the body of the carb.

Filter? Are we talking air or fuel filter, and if fuel, is it the filter in the tank or in the carburettor?
