G'day, and many thanks for all your 'How to' videos. They do help when there is so much rubbish being put out there. Regarding the muffler holes: call me dumb but did you enlarge them all? My local Bunnings didn't know what sieve mesh was. Oh dear!! The side adjuster and dogs do make a difference to a handy sized MS170.
I've done the side adjust and fang on my 2 170's. I have not done the exhaust yet and may never. Good video though especially the bit about making the exhaust port holes too big. :-)
I'm told that mesh size 20 is 1mm holes and depends on where you buy it its available in a sample size for under $6. Larger size e.g. 300mmx300mm around $22 Australian - free shipping on most.
It most likely breaks regulations am sure. Anything you touch on any exhaust will break manufacturers and government regs. But that said it runs better
All I did was change to bigger mesh so the saw will breathe a litter better and retune low and high. It runs slightly better not a huge Increase but better small Increase than no increase
I drilled the dead center hole and far left, far right middle holes to meet their corresponding holes, kept the stock screen and flared the vents slightly. I knew that goon that carves out the entire grid ruined his saw.😅 It's amazing how ignorant people are to air/ fuel ratios. Anytime you open intake or exhaust on an engine, you're leaning it out. Lean is mean... until it's burnt up the motor.

I just bent them outwards a bit gave it a tad more space
How many of the 3mm holes got enlarged to 4mm?
@blueyhanson6253 all of them

great info and video , the dog spikes ?? , stihl, or ?? , another great poster is donyboy 73 , he says and shows the part # s 4 the saw ... thanks!!
Yes Stihl dog spikes
I had to drill my screen.I will look for the bigger screen the next time I'm at the hardware store.
Yes drilling can work also pulling out every 2nd or 3 rd wire also works
@@ChainsawUsersI've found since switching to a cleaner oil I don't have to clean it as often.Thanks for this channel.
My buddy told me to use size 20 stainless steel mesh.
@johnchuck9573 a few sizes up will do the trick 20 stands per inch sounds about right
Did you keep the stock carburetor when you did that exhaust mod or did you ring out the main jet or you keep everything bone stock

What is the size of t spinner you used for muffler nut
Muffler nut is standard fitting
6mm
@@ChainsawUsers thank you so much dude 👍
I had 8mm and no net at all.
Did you adjust the carb afterwards?
No because it just breaths a little more. Many people go to far with these mods and yes they require tune up

That said means bark box egan straight shot will all lean out the motor. I only flared the vents also just a bit
