What causes a saw to not want to idle?

What causes a saw to not want to idle? Happened again..

Ran fine the other day, it started on first fire up after piston and cylinder replacement. I did replace the base gasket, it had a paper gasket in it, now its got a metal gasket.

Impulse tube is good, intake boot is good. Diaphrams in the carb are good, new fuel filter. New plug and spark plug wire.

It runs great half and full throttle, but wont settle into a nice idle, almost always sputters out. Ive messed with the needles, started at 1 turn out and adjusted from there.

haha, I got pissed and goosed it a couple times hard and its run fine since. Im thinking there may have been a small piece of chit in the low side, and I got it blown out.

Would like to hear anyones opinion about what happened.

EDIT: It started acting up again. Was out milling some siding and got about 3/4 gallon through it, and it started again. It runs full out fine, just wont idle. It slowly burbles out. It wont start unless I have the trigger pinned at least half way. I dont have a clue.

Sounds like just what you said, some garbage in the low side. The ole blow it out trick worked like a charm for ya, can't beat that. Good job.

Cool. The town sure has changed alot in the past 5-10 years. Houses everywhere. They are starting to call Leesburg the new little DC. When is the last time you came through???

Last summer, took my son to DC for the first time, he was 2. Frederick is growing too. When we moved there I was 16, you could go to 7-11 without waiting in traffic. Now you can get out of your parking spot without waiting for someone to get out of your way.

Your so right, Northern Virginia has become a rat race for sure. Next time you come through Leesburg look me up, we'll have a pepsi and talk some saws............
