So, your first experience with check spark was good?

Yep I even used my old way to make sure I didnt have spark.   Checkspark was much easier, I just didnt trust it yet being it was 1st time using.

Just always make sure you clip it on the wire and not on the boot.   It will not work if even partially clipped on the boot.

I did try it down on the lower end slim part  of boot where plug wire enters boot. Worked there.

Received some feedback from the work I did on the above 338.  Owner of the tree company sent me this in PM here and hope you dont mind me sharing the info. 

(( wanted to let u know.......saw is hanging in real nice now.....cold starts in 2 to 3 pulls.......more often in 2......u did a great job.......thx ))


Just glad to see the carb fulcrum adjustment, carb tune and replaced intake boot did the trick.

Good job Kevin.
-Aaron

For older saws:
Tune the H side so that it 4-strokes (burbles) at WOT unloaded and just cleans up when under load.
When you lift cutting load, the saw should immediately revert to 4-stroking.  Fine tune the transition point for the wood you're cutting.

Husqvarna 338xpt I been working on troubleshooting on my spare time. Rebuilt carb, thinking carb issue and was thinking of ordering a new one. Since no change after rebuild. Checked intake boot it wasnt tore like I thought it would be. So I started thinking seals. So getting ready to pull motor, removed flywheel to get started. What a find. = big smile. Now if the piston isnt scored up I will be very happy.


impulse line  503842601

So the impulse sits under the flywheel.    Alright way to go.

Thanks for posting Kevin. I've never gone that far into my 338XPT NE.  Interesting built saw. Looks like a mad scientist designed that saw making everything fit into that compact chassis.
Mine hasn't been running all that good lately. Now I know what to look out for.

Yep Roger. The impulse line had rubbed a hole against the flywheel and came off at one time.  You can see the rubber on the back of flywheel too.  Saw is dated 2012


Willard here is some older pics of the other 2 I had.  Got to pull flywheel to take motor out the other side.   Then can replace a boot too.

That thing is sure dirty.   The boot pulled right in half also.    Should do real well when our done.
