Where can i find a service center to purhase a chain adjusting assembly for a poulan 2055 chain saw in the tampa area

You need to adjust the low side out a quarter to half a turn.

H I ONE quarter turn L one turn then adjust the idle.

Take the exhaust off so you can see the side of the piston, if it is scored or damaged it means it has probably been run without oil added to the petrol.
That can cause the problems you are having, if it is throw it away, its not worth repairing

Take a lenght of welding wire or other stiff wire, bend the end around to create a u then enter into the fuel tank throught the filler hole, hook the fuel hose and carfully pull out through the filler with the filter on the end, the hose will be long enough to do this, just pull the filter off the enf of the hose and re fit the new filter.

A typical fuel system and a couple of suggestions follow:

An example of an IPL for a "2055 Gas Chain Saw Type 7" follows (may not be your saw):

If not your saw, yours can be found here:

The dash number of your serial number is the type.
I am reasonably sure the upper most carburetor connection (it bleeds any air in the carburetor, air rises) goes to the primer. Leave the hoses long enough to swap them and try it. They can be shortened once you verify the correct routing. Good Luck. HTH

I think this is the what you seek:
http://www.ordertree.com/modelinfo/PWE/PP4620AVX-Gas-Saw/75.PP4620AVX-Gas-Saw.1.59.1.html
The "Handle, Chassis, and Bar Assembly" detail
Items 63 through 69 are parts, I think item 70 is a complete assembly ($22.78 without a kiss).

Your saw without tooless adjustment.

Item 64 (complete assembly) $2.53.

If my saw I'd ask if it can be modified!!!

i have a 4620 poulan that had the same problem. use it for 10 minutes, spend 15 minutes reinstalling the chain. i sent poulan an email threatening to sue them and they decided to send me the parts to change it over to the old style for free. try poulan.com
