Ported mufler on johnny 2171

[procutter]

Will a ported muffler really make a noticeable differnce in this saw and what adjustments will need to be made to the saw after installation.

I think muffler mods have been talked about once before.

Sorry dude, Seriously, open up the muffler to no more than about 80% of the exh. port window. and turn your High speed mixture screw CCW to richen up the mixture. What you want to hear is a 4-stroke burble at no load WOT. By Doing this mod you will gain about 10-15% more power. let every one know how it works out.
No offence was meant, but this same question is asked every single day.

Agree, but I think you are a bit optimistic on the gains - could be wrong though.....

Yes Sawtroll, your probably right. I think it was the beer talking the other night. But properly modding the muffler along with richening the high side needle will yield noticeable gains on most saws.
This morning I was reading a thread on another saw site, the subject was
"debunking saw mod myths" it was very interesting. I would post the link,
but there server seems to be down at the moment.

I have a question that hasn't been talked about before:
If a wild bear, (with severe gastritis) vents in the woods on a foggy night, will I be able to hear it from your house? :smoking:
