That's it. I looked around for a couple of minutes on the acres site earlier and must have missed looking at that one.
The little 2000/2.0 wants to run. I pulled the top and bottom covers off the carb and got all of the bar oil out of the carb. The diaphragms aren't stiff, but it's still not pulling fuel. I'm wondering if the fuel line is leaking air since it's not a very tight fit on the carb inlet.
Those little saws can have trouble pulling fuel.
Here's from some recent posts on the issue:
Working on a Poulan Micro XXV thats been sitting empty (no fuel - no bar oil) for about 6 years. Put on new fuel lines and filter (thanks for the tutorial Modifiedmark) rinsed the tank with fresh mix and refilled. Primed carb and started 5 or 6 times - won't draw fuel up to carb. Carb kit??? Suggestions???
Carb kit is probably a good idea since the diaphragms may have become stiff. The gas cap also has a vent that needs to allow air to enter the tank as gas is pulled out. You could just loosen the cap a little to test that.
Good advice there. I'll add that the Micro is a saw that REALLY needs a healthy pump section in the carb. It has to pull fuel through about 15 miles of fuel line. New diaphragms/gaskets and screens (and a good cleaning) will help.
The earlier fuel caps are also crap. Either they pee fuel on your hand/leg/etc, or they don't breath and the saw will starve for fuel. The current replacement caps are much better and are about $5 and change at your local Husqvarna dealer. It should be a stocking part because of the Husqvarna 23 (rebadged Poulan 2300) and the various rebranded Weedeaters that Husky sold for a while in the 1990's.
530014347 is the current part number for the cap. Here's what it looks like.
