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. :-)

Yes Stihl dog spikes

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

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 had to drill my screen.I will look for the bigger screen the next time I'm at the hardware store.

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

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.

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