I dont think this carb is one of them and not your issue. But using high pressure air can ruin some carbs. 

Kevin the WA/WT carbs are in that "can be ruined by high pressure compressed air" camp.

If a crank seal (or both) is bad, the saw will have weak impulse signal.  These saws have a LONG fuel line.  If the pump section of the carb is sketchy (old diaphragm, diaphragm/gasket in wrong order, plugged screen) and/or the impulse signal is weak, they won't pull fuel well at all.

Seals are 530019059, available from Poulan and Husqvarna parts sources (same #) for about $4 each.  They're easy to change too.  Aftermarket # for these seals is SKF4913.

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.

Another thing to check is that the fuel line was not pinched when the handle was reassembled. Did that one.

Ok, still no luck with this carb - I'm at the point of swapping carbs - its about the only thing left for me to try...I cant seem to find the WA19a carb for this thing - a google search informed me that I can replace this WA19 with a WT309 - the pics seem to show it as almost identical...however, before investing in a new carb, I'd like to see what the EXPERTS here think...SO:

Q: is the WT309 a direct replacement for the WA19A?

Thanks again guys - I value your opinion a lot more than you realize!!!

I'd have to look at both carbs.  I don't have the carb #'s for the Micro series sorted out.  If the throttle bore and venturi sizes are the same, the fuel line barb is in the same location and angled roughly the same, the impulse hole is in the same spot, the throttle arm is the same, and they have the same choke setup..................then I'd run it.

DAMN!! do I feel like a boob or what!! (but then again, boobs are a good thing, right?)

Seems that when I put the carb gasket on (ie, the one I had to fab up) - I neglected to punch the PULSE HOLE in it so the carb can pump fuel....

Problem solved now - I'm just glad its the little things ....sigh!

Thanks for all the input guys - sorry to have wasted yer time with this mickey-mouse problem!!
