I was reading about some Jonsered (?) that had a stepped exhaust port floor, so I decided to try it.
No lathe work (I don't have one).
This saw is headed to Georgia on Monday for tree cleanup.

How will you retain the head? Long studs out of the crankcase?

What’s the material that the O ring is made of ?
Yes, long head bolts.
Want to say it is a viton, but not 100% sure. Just bulk material, cut the ends on and angle and match them up seems to work well.

Facebook is killing all the forums. And I got burned out on posting pictures of saw work a long time ago.

I like seeing all the different ways people do their port work, I see you only remove part of the lower extension some remove it all and others remove none of it. Some guys mess with the upper transfers others just clean them up and aim them a touch. Some guys are lowering the intake some but others choose to notch the piston to get same effect on the 201. I’m doing my first 201 this week for my friend at the tree service and I will have more so trying to figure a good method. Doesn’t need to be the best but close to everyone else’s and reliable. First one I’ve already removed the transfer extension.
