Chainsaw Repair

I ran the saw again.  I checked the fuel line (which is new) and it was not kinked.  Very straight.

The filter was moving around in the tank just fine.  To rule this out, i used a completely full tank.  Same problem. I also opened the fuel cap and re-closed just before tipping forward to rule out any vent problems.  Same problem.

Then, i started messing with the low side needle.  I think i straightened it out.  I believe the final settings were richer on the low side than originally.  Now, the saw doesn't stall when tipped forward, so i think i fixed the problem.  Does this seem possible?

I have to assume the strato design has made tuning a difficult thing for me.  I just wish i had another 455 beside it to compare to. 

The idle is not perfectly steady.  It goes from around 2500 to 2700.  It's not really audible, but it shows up on the tach.  I let it idle for at least 5 minutes, so i know it won't stall out.  It also has no hesitation on throttle even after extended idling. 

Any of this sound like a problem?
