Sorry to leave questions unanswered...been having interweb issues the last few days. Going again now but about half speed gotta badger them some more...
Windthrown....you will find that most every part for your Jonsereds is NLA....as are parts for all older Jonsereds...so if yours is in good condition use it gently. As much as I don't like that series they still hold a place in the history of the brand and are important for that fact alone.
As I understand the history timeline is... Elux bought Jonsereds out in 77-78.....however at first they were allowed to continue right along as before....producing the 49SP, 52/52E, 621, 70E, 80, 90 and others that were proven designs. In terms of production Jonsereds was rather efficient.....many parts of the same parts were used on a lot of different models.....for instance.....the trigger handle for a 49SP will fit all the afore mentioned Jonsereds models...except the 621. Ign were the same for many models as well...52E and 66E/70E used the same ign modules and coils.....if you look at the IPLs you will find different part numbers....this is only due to different lengths of wire attached for different models. Points igns were the same for the 52, 621, 80, 801, 81 and 90. This type of production makes them cheaper to produce and makes it a lot easier for us to keep these out of production saws alive and running.
Now around 81 Elux started to get more involved and change the production and designs...this is where the 510Sp, 520,525,530 and 535 come into being.....none of these 49cc saws held a candle to the 49cc saws they replaced (52/52E and 49SP) They did make some short run saws that were pretty good at the same time though....notably the 451E/EV which was designed as a high speed pro limbing saw and the 910E/EV which became the 920 and 930 quite quickly. But basically these decent saws were doomed as well by Elux deciding to combine Jonsereds and Husky production around 1983 which brought us the first 630 Jonsered
Ebay saws are what they are.....I have gotten some really fantastic saws that looked like junk for realy sweet prices........I have bought really nice looking saws for good dollars that turned out to be junk...just pretty parts saws. Got shafted on a 910E that had been underwater too....about the only useful parts were the plastic ones. On the other hand... I bought a 90 that was strictly a parts saw....the guy contacted me before I even received the saw and apologized for the condition and would refund some money.......when I got the saw it was rough but the parts I needed were fine.....I got back to him saying I wished the saw had been in a little better shape but was fine with the deal none the less......the guy refunded the whole price except shipping which was like $15...so I feel I break even on ebay.....never had to file a complaint....though I could have on the 910E....but never pay much for a saw either...
So in the Jonny history timeline, when did the 'original' CO fall? Here in the PNW after Mac didn't take the proper cues from European saw technology and fell(for loggers anyway), Sthil and Husqvarna reigned supreme. But slowly through the ranks the perky little Jonsereds started appearing in the back of logger's trucks. They never replaced Sthil and Husqvarna, but they were at least on the job sites, cleaning up on the landings etc, which speaks volumes. Yeah, a lot of my NOS parts have come from Maine, so I always had a sense they were hugely popular there.
