At a glance, I'd say no. Acres info is limited, but a model 70, which is supposedly the same, shows a slightly longer stroke. I suppose the way you would truly know in the absence of IPLs is to compare them side by side.
I thought you might like to see this 642 I recently resurrected. The saw was in pretty good shape, except for some bad corrosion on the bottom. It came to me with another crankcase and I ended up using 1/2 of the original and 1/2 from the donor to come up with the best kit. This saw now just flat out runs and cuts. Amazing what 106cc's will do.
I took it along to the PNW GTG last week and several guys tried it, everyone liked it.
I picked one up last week through an online auction site, very low hours but it looks like it was put away under a workbench after a hard workout and forgotten there for 30 years. I wanted to give it a thorough going over before I tried to run it.
In the process of cleaning it up inside and out.
If you've never been in one, the starter mechanism is pretty complex.
Trying to remove the years of neglect.
I took the oiler apart in the process of dismantling the saw and two springs and check balls magically appeared. I am hoping an IPL will give me some guidance on where the part go exactly.
The Solo 70 is done. Starts, runs, idles, oils, just not quite as impressive as the 642...perhaps a better bar and chain would help. All of the saws from this lot (auction last week) appear to have been run very little, put away dirty under a workbench and forgotten for 30 years or more. Some of the accumulation does not want to clean off with mineral spirits, Mean Green, Purple Power, or Greased Lightening.
The greatest tragedy in the process was the broken knob for the AF cover came apart.
The wide, hard nose Oregon bar did clean up nicely as well. Chain is classic .404 chipper.
