What is the spark plug gap on a Poulan pro 260 chain saw, 42cc?

SOURCE: chain sprocket

I looked at a breakdown for the 42CC not sure if the same one or not but it appears that the chain sprocket is held on by an Eclip and behind that a flat washer. If this doesn't look like yours give me the model number and I will research another breakdown

thake the muffle off and look inside the hole at the piston.if you see any marks on the piston,the saw will never start.you need to change the piston and cylinder assy.the cost is about $150.00 for the parts.that does not include any labor cost.most of the time it's not worth repairing.let me know if this helped or not...................................

Start at 1.5 CCW form lightly seated then tune for performance like this:

CW is leaner; to lean will destroy the saw. If over tightened closed (CW) the adjustment screw faces are easily marred; marred adjustments are difficult to impossible to set properly.
Clean the air filter; adjusting with a dirty filter can cause a run lean condition once cleaned and the saw run.
There are 2 wav (sound - idle & full – may not be highlighted) files that I find most helpful, I think you will too.

I think your starting procedure may be the cause of flooding. Flooded is the #1 cause of hard starts in 2-cycle engines. Read carefully the recommended start in your manual. most miss the second note. It should be similar to this (read 3, read it again):
Warm start in the manual says 1/2 choke BS. Close choke, (sets fast idle) open choke, pull rope.
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).

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) – Do not pull with choke closed.
4. Push (open) choke, pull starter until it starts (usually first pull).

Testimonial: "you'all have been very helpful.to even ask a question at a repair shop around here you must first hand them your wallet! Thank kindly"

you have 2 screws marked H and L. With the engine running, turn the L (low) screw for best idle. Then for the H (high) screw, Hold at full throttle, turn screw, and listen for smothest and fastest revs.
