What oil do you recommend?

For popcorn or chainsaws?

For popcorn or chainsaws?

Is there a difference?

 

[farminkarman]

Is there a difference?

Well, I don’t like using coconut oil in my chainsaws, so I guess so

How do you remove or put on clutch cover? Remove the pipe?

Doesn’t even look like it would fit underneath the pipe in that photo

Joe, do you dyno a saw with muffler mod before porting, so you can see what your port work did? That's usually my approach, so I can see gains (in wood for me) with muffler mod, then gains from porting, then gains from compression.

It's tight, but it fits and can tighten the bar nuts.

With these pipes just 1 spring keeps them attached to the header flange. Easy to pull the spring and slide the chamber off quick.

No, not unless it comes in with a muffler mod.

I normally do stock, then fully ported.

Lot just depends on the saw too. The 20% gainers 5-10% could be muffler alone.

OMG awesome work Joe! Great video with fantastic explanations. Lots of time spent on your part. Thanks!

One spring for pipe removal and install sounds 75% easier than trying to remove four loctited bolts just to get the cover off.

Make sure you have the hook tool to pull the spring off.

Even the backside of cutters and rakers will do a number at full force...

That’s true too.

The hook tool is pretty common also for snowmobile exhaust systems. Some of them have 28 springs holding their pipes in place.
