Wow super nice how to's with pics.   Thanks for sharing info.

if it does not help, easy to change back to what it was.  three dollars in parts.  right now, it's not helping.

currently stick expoxied two of the 3 additional holes shut.  leaving a single 0.060 inch hole and 0.020 inch indent.  this made the saw idle too slow, (with throttle butterfly completely shut).

as the holes were closed off, the effect of better mid-range to better high rpm operation decreases.  disappointing.

to try to get some of that back, increases single 0.060 inch hole to 0.073 inch.  testing this change tonight, the idle speed is just below clutch engagement.  runs pretty well at mid to high rpm.  but again, it's not nearly as good as with all running all 3 additonal holes.  you win some and lose some.

another thing to mention is the sudden stalling lack of fuel after idling for about 30 seconds, after test cut.

don't like fiddling with metering springs to get more fuel delivery.  anyone have some ideas?

gotta think about this over a beverage.

will post some pics of this.
