Part Six: The Exhaust System

Sneaky Pete tuner pipe

Call it the sneaky Pete uterus port.

I remember someone adding baffles of sorts to the inside of a tube then welding it in a muffler. Seems like it helped tone down the pitch some.

I'm gonna be putting metal roofing on today. Maybe tomorrow too.

I'll start the next thread when I can.

Those look great, you could probably get away with selling a few, especially if you make a few sizes.

Thanks. I had the thought of selling some but didn't want to "muscle in" on other members already selling their deflectors. Just a perception I want to avoid.

Understandably so

I put new translucent panels on my barn last week. Hope the pitch is low so it's easier on your legs. Be careful up there boss.

lol, maybe @Hedgerow can put up a pic of the muffler on his 346...

This LOUD one?

How can 80 percent of exhaust port opening be calculated

With uncooked spaghetti noodles. Put as many as possible through the exhaust port, then keep 8 out of every 10.

I remember that one. Who came up with that anyway?

Ok, let's talk about this. If he carved a BIG hole and smoked the saw. It must have run leaner, which in my eyes is burning more efficiently and completely. Should make more power...being it would get tuned properly

That's exactly what happened to that large saw which was almost brand new at the time .Problem being he did not retune the carb ,it ran fast but not long after that .I think it was an 880 but it could have been an 088 ,like ten years ago .I doubt seriously at the time he peddled in on flea bay if it fetched more than 300 bucks .At one time you could find some cheapies on the bay not any more .Those two Mac 125's I own I have about 100 in one and 125 in the other one,90 in a pristene Mac 105 that had the original chain and 24" bar .Sat in a repair shop for over 20 years needing a recoil starter . Those days are gone

This is kinda weird because the 088/880 is damn near impossible to lean out it seems. Mine is ported 088 with unlimited coil and it still four strokes with the h screw 1/4 turn out

I am liking more quiet these days .

 

[mdavlee]

I kind of like stock saws for firewood anymore
