026 Pro Questions...

[Nicholas]

Good day to everyone,

I am in the planning stages of replacing the non-adjustable, fixed jet carburator on my brother's 026 Pro. I understand the equivalent, adjustable jet carburator is the "WT-426". During the carburator replacement, I also plan to change out, examine the following items:

- Fuel filter/Fuel pick up assembly.
- Air Filter Element.
- Spark Plug.
- Clutch Hub, and Rim Sprocket.
- Check ignition/coil gap, correct if needed.
- Clean carbon, and residue out of muffler.

***My question to everyone: Are their any other parts one should examine, or replace while the saw is disassembled?***

Any advise would be greatly appreciated.

Thank you.

Respectfully,

Nicholas

Nicholas-

You might check the chain tensioner assembly, make sure the tensioning shaft is still straight, and grease those parts. If it's an old saw, have the muffler sandblasted inside and out and repaint it with BBQ black. Blow out your starter real good, lubricate behind the rope rotor with dry graphite or white lithium grease, check the pawls.

The 026 Pro has an intlli-carb. When you swap on an ajustable version, you have to re-use your diaphragm cover, otherwise there will be an open hole in the back of the air filter.

Check the impulse hose, they are notorious for cracking.

If you are going to be that far into the muffler why not modify it and enjoy the added power!

Good Day to everyone,

Thank you for the many informative replies. I have one additional question though...

***How does one go about properly modifying the muffler?***

The muffler appears to be pre-EPA approved, and has no heat reflector plate in front of the exhaust port/outlet.

Any information would be greatly appreciated. Thank you again.

Respectfully,

Nicholas

The best place to start with the muffer is to remove the cover and spark arrestor. Then with a dremel, gut out the opening to approx. 3/8" x 3/4".
Another method is to simply take a 5/16" drill and drill at least 4 -6 holes directly thru the existing holes on the muffler cover.
Dont over do it, or loss of power will result. You want a total exhaust area approx. equal to that of the area where the piston meets the jug at the exhaust opening on the cylinder. Experimentation is the key. Find or buy a muffler cover and play with that till you get the figures just right.
Hope this helps
