MORE Power!!!

[MasterBlaster]

What does it mean to 'open up a muffler'? I allways yank the spark arrester on my climbing saws, but I'm guessing theres more to it then that.

Is this something my 066 could benefit from?

I did a 'saw modification' search, but didn't find what I wanted. Anybody know a good thread discussing this?

Try searching for 'muffler mods'. By Gypo's rule of thumb, the muffler opening should be twice the area of the exhaust port. if you make any mods, you'll need to readjust the carb.

The best way to help out your 066 is to buy the Magnum front cover. This will give you the right dimentions for your exhaust port. You will need to richen up the saw a bit due to the increased flow and Hp you will find.

Later,
Chris

Thanks, sthilman036 - gotta ballpark figure on what that Magnum upgrade will cost?

Walker has modified mufflers for 120.40 Can = 86.05 US as quoted by them. Probably worth it if you’re a klutz with a grinder.
I’m trying something different, a billet machined muffler.

Prices must have gone up. I paid $50 for two a couple years ago. Heck it only costs $100 for the full Walkerizing doesnt it?

The 066 front cover with the screened outlet is nigh unto $40 in the lower 48.

Hey, Huskeyman, what does a 'full Walkerizing' involve?

You'll get more power if you take off the air filter too, but you don't want to do either. They both keep stuff out of the engine.

To completely Walkerize any thing is 200.00 Can = 142.95 US quoted this week.

They do slight porting, shave the jug for a little more compression, clean up any burrs or casting marks from the factory, and of course the muffler work. I think their website is www.walkerssawshop.com

Sorry I was gone this weekend watching my better half tair up some wood at a lumber Jack Festival in Loyalsocks, PA. I will check to see what I have in the stihl pile of parts. I might have a 066 Mag muffler cover. I need to know if the bottom front part of your muffler is flat against the oil tank or has a little rise under their for air flow. Or you can give me the age or cerial # off the saw.
Thanks,
Chris
