Jonsered Saw Models Built On Husqvarna 372 Chassis 2065 , 2061 , 2071 , 2171 , 2166 , 2172 

Yes, some principles/tweaks like a little ( not too much and also saw dependent as some have bottom ends stronger than others ) compression increase work across the board, others are more cylinder/saw design specific. Tried to explain to another saw guy recently that you have to step back and see these as an exercise in thermodynamics and then they make more sense, especially the new ones.

Yup same crank / bearings etc. as a 372 with a whole lot less energy applied to and thru the crank with their open port and smaller bore cylinders.

@@afleetcommand My 362xp is a closed port but not quad port like the 372xp. Just two good sized ports

Yup a cylinder unique to those saws too BTW. Bob wants me to "give it a try" and I want to build the 2163 with a 48mm :) A dilemma

@@afleetcommand hmm maybe a comparison video that would be interesting

My current play saw is a 2065 with an aftermarket 52mm piston and cylinder. I saved this saw from the trash can with help from your videos.

2010

Have an article from the late 1970's where that essentially was a build concept for a Jonsered 111 based race saw. But on these things I would ask what is the definition of win? For me on this channel it's cost effective fun and useful saws where there is interaction with saws the hobby folks with typical tools and skills can also do. I have never focused on the "Showing Off It's All About Me" type of freak show or pure race saw video's where I do things most who watch can't or wouldn't derive a benefit from. What I have as a core focus is simply enabling other folks, not selling my shop or skill's. Showing folks how to interact with their favorite machines themselves, not promoting my particular skills as tool. I RELUCTANTLY put in lathe things from time to time because I HOPE as growing part of the hobby saw community moves there in their own quest. Help folks stretch their boundaries. When I see that is more typical, I will do as I did with "enabling" folks to learn saw mechanics by building kits, and split cases, I will add more sophisticated machining projects :) Until then? Machine work stays a little "dark" and more tools from Lowes builds happen. Right now the focus on the Autotunes for regular folks theme.

@@afleetcommand I think that I understand. Thanks for your consideration as for as taking the time to give me a reply. From the mind of Tacotodd 👍

yes. Can bolt all the cylinders from those original edition versions right on

@@afleetcommand ok but is the crank unique to the 2063 cases like the 562 crank won't work in the 555 cases because of the large vs small mount situation the length is different if I remember correctly from one of your videos of ultimate old man saw.

You have a point, the 555 & 562 cranks have two area's where they differ, one on the clutch side as the oil pump is all different, the 555's are essentially like a 550's so that end of the crank is all different to accommodate, AND the 562 has stuffers while the 555 does not, The stuffers require a little more clearance side to side so the crank is machined differently to accommodate. I don't think a 2163 has stuffers, I could be wrong so when we "crack" that saw we will see for sure. And I think the clutch & oil pump are dimensionally the same on the 2163 where they hold the bar oil pump & clutch as the large mount saws. I COULD be wrong, buy I think they have the same crank. WE WILL SEE! When I get into that saw :)

Change the tank vent

@@afleetcommand I'll give it a shot, thanks much

It will have it's own video a little later in the winter. :)
