About the same for me .When this thing showed up all I had close to it was an s-25 Poulan and it would walk away from the 011 Stihl .

I looked at the IPL and from what I can decipher this is a real old type  of design which is surprising in 1981 .Oddly it shows the rod and needle bearings sold as a seperate unit from the crankshaft which I found odd indeed .Unless it were made in such a way it could be disassembled without special tools  which I've never seen on any saw with a captive rod .

Like I said for no larger than it was it cut okay but did not exibit that typical Stihl zip .After looking at the design it's very evident why .It was never designed to be a race horse .

Even the current 211 has a slide off removable rod and a single counterweight crank. I think it is the same cc as the 201T?

 When you pull the jug on the 011. You need to be extra careful or you will loose all the big end rod needle bearings into the crankcase. Ask me how i know...

Does that crank pin just fit together or something ? I mean I've been to two county fairs and a goat roping and I've never seen anything like that .

the cranks only have a counter weight on one side. the rod will just un thread off the crank shaft and off one end. if you wiggle the rod, the rollers fall out. you have to put it together with wheel bearing grease to keep the rollers in.

They are just needle bearings that are loose in the rod. I had to use grease to hold the bearings to the crank so i could slip the rod end back over the crank. PITA

I understand about the bearings but I don't understand how you get the rod end over the pin .

Now I can possibley see where you might be able to slip rod in  place on the side opposite end of the counter weight  and drop the bearings in from the throw side but then what keeps them from slipping out sideways ?I'm missing something here .

This is one odd design .The thing shows needle bearing mains both sides .Kind of  like an 020/200T with the roller bearing mains .I got no idea how they hold the side thrust unless it's got fiber thrust washers  in the mains  like the 200ts' which are the weak link in that design . Why good heavens the longer I look at this thing it's a wonder it holds together at all .

The piston/cylinder holds the rod in position.

There are slight shoulders on each end of the crank pin location.

As long as the rod is in position over the crank pin, the needles or rollers cannot come out because of the shoulders.

At assembly, the needles or rollers must be stuck onto the crank pin with grease so you can slide the rod over them.

At disassembly, you cannot get the rod completely off the crank unless the crank shaft is completely removed from the flywheel side of the crankcase.

The 35 and 40cc Quadra engines from North American chainsaws of the late 60's through early 80's were made this way. They were used in the more modern looking Lumbards and other chainsaws of the period. These chainsaws had a clamshell engine design but the cases were metal as plastics still were not stable enough.

I've got a couple Lombards but they are of the Al-42 series design .68 cc or something .I'm not certain about all of them but one that cooked it's top end is in a box  and has a pressed together crank much like a Stihl which I found surprising for circa 1968 or so .

You look at some of these designs and wonder what they were thinking .Like McCullochs grand plan of using the piston pin bearings pressed into the outside of the piston rather than on the rod end ,terrible idea .Then on the other hand the danged things held together for years so it obviously worked .
