At least, it is either 70, 70E or 66E - there is no way it could be anything else, I believe, including the 90 and 801 - unless it is a total "frankensaw".
How do you distinguish the 70, 70E and 66E from each other????
I aso believe that at least the 70E was made for a long time, and there could have been some smaller changes during production.....
I asked that fella about that saw. He claims he got it from the original owner and that he had changed the top with a 70E. But, I believe it is a 70E as I have 2 with the spark arrestor muffler, as it does. I am sure motorsag would know for sure, he told me once he could tell which model it was from 200 feet. And I believe him! Bob
So do I - He is the Jonsereds GURU, but he don't post here too often.
I don't think that the screw holes in the filter cover of the 70 will fit the case of the 90. The right side handlebar attachment (or whatever it is called) of that saw is also not consistent with the 90 or 801, nor is the bottom part of the rear handle.
