Echo PB2100 blower problem

I have a Echo PB2100 that I have had for several years. Just recently, It started running sporadically and uneven. I ran it for quite some time without an air filter..and since I'm not really in a dusty environment..I didn't worry too much.
I just purchased a Zama carb for the blower...and I gotta say...I installed it and he blower started up just fine. A little tweak here and there...and it ran beautifully. Before I installed the carb, I did a thorough cleaning of the unit to rid it of all the built up gunk over the years. Since it was all clean and running great, I brought the air filter out of storage and installed it. With the air filter installed...it will not start. Take it off..and it starts first pull. Is there any advice on how to resolve this issue? I wanna start off with the air filter in place. Heck...I switched to Echo gas and everything. I'm trying to do this right...but it's not cooperating. Thanks in advance for the assistance.

Strange, I would suspect a gas or oil soaked filter, or something wrong with the filter. The filter shouldn't interfere with the flow of air enough to keep it from starting.

The filter was new...but it was never used. It was in a Tupperware container for a long time! Air tight!

Can you easily blow through the filter?

Well...lets put it this way. Even when I take the element out...and screw on the housing...the engine wont start. The heck with the filter....it only takes the housing attached to prevent the blower from cranking!

Now...I started it without the filter housing...then attached it...and it kept running. I'm not sure if the screw going into the base housing is impeding the choke from working. I'll check into that as well.

When I tightened down the air filter cover...the screw was protruding into he path of the choke lever. I extracted screw from cover..placed some washers under it, basically shortening the penetration and the choke was able to move freely. I'll wait until the unit cools down and retry again when it needs to be choked. This would explain why the unit would not work when cold. I'll report back!

Ta Da!!! It works! Sometimes, the simplest things! I'm not sure how the screw all of a sudden impeded the path of the choke lever, but the washers did the trick.
