Unit started extremely hard and would not run full-throttle.

Remove the carburetor and replaced all gaskets, fuel pump diaphragm and regulator diaphragm. Reseated bulb and replaced the gaskets which mate the carburetor to the engine\'s intake manifold. Once completed, I tightened all the bolts on the crankcase and engine head, replaced and gapped the spark plug. The unit started on the second pull and is running great.

A quick note about the Walbro rebuild kit and the original parts in the carburetor. The fuel pump, for these carbs, in the original was a piece of blue plastic/mylar(?) that was solid. The replacement fuel pump looked like a mesh screen. That had me confused, for a bit. I did not realize that the replacement parts would look so different from the originals. That said, I should laugh at myself because this unit was made in 1996 and this is the first time it\'s been rebuilt. Things have changed, a bit, since them, obviously. LOL.

This was a quick, and easy job. If you can use a screwdriver you can do this work.

Confirmed the saw had ignition spark before I ordered the Carburetor rebuild kit
Removed the old Carburetor and laid it on a clean work surface (old cookie sheet works good)
Disassembled the Carburetor being careful to lay out all parts to assure proper re-assembly
Slightly cleaned interior and exterior of carburetor bod y with carburetor cleaner spray and air
Reassembled the Carburetor with new parts
Reinstalled Carburetor on chainsaw
Primed it ... Saw started and ran like new with very little tweaking
It was an old saw, tough to find the carburetor, ordered the rebuild kit by the Carburetor number-
Cost 1/3 of a new carburetor....piece of cake...I\'ll continue to rebuild over buying new.
