*after a dealer overhaul from a stolen/abused/recovery situation, which led to the 2150 purchase. Lately I had stud issues with my 2150, and got that temporarily fixed (it unfixed itself), and the MOMENT it started sucking air (apparently) and I couldn't get it to tune properly--I yanked it apart. I have learned to pay attention to everything, and overspeed/irregular idle are not to be ignored eh? And all my German saws are down right now-aren't sparking apparently. And it's the middle of my firewooding season. So I've purchased or have on order: jug/slug/adapter 45mm closed port, bearings/seals, bar studs 2150, boot and clamp-trying to get a saw going. Going to get a new pressure/vac gauge if I can't find my old one (workshop is in transition, shut down presently). 2145 is the current (was until this morning) project. I've never been this deep in a 2-stroke, only automotive/diesel stuff. When I got the top off I noted that the crank was not easy to turn. When I got the crank out the bearings felt fine, but the case isn't so great and that one bearing is losing it's cage and the cage metal has been floating around in there. I do remember a muffler coming loose once and snugging it back and going on with it. About my other wood-fetchers: Thing is I got "into" bigger saws with my pawn-shop 7900 and the "parts box" 116s (Sachs Dolmar) and used them a lot in the last 10 years. Then the 7900 lost its fire a couple years back and the 116 did apparently the same, just a few weeks ago. Right after I pulled it back out because the 024 lost it's spark. I had falled back to the 024 for a couple or three years of late. It was old and reliable. The 2100 is just a bit heavy for firewooding and I've not started it in a handful of years--thought I was going to mill with it. Did cut and buck a few logs with the beast. But getting into the bigger saws took most of my attention away from the 50cc-class. Just hadn't had saw-fixing money for a while and now a have a little bit. So I'm thinking a good cleanup and epoxy patch might work to save this case, but I'd like the learned and experienced to glance at it. I wouldn't expect a proshop to build on this case, but as the owner/op, I think I may as well give it a shot. I'm afraid I've missed the market on second-hand 350's/2150's and parts. BUT I'M KEEPING AN EYE OUT! These were great saws for me, as I'd only ever run the 024 since a teen, and bought these just for firewooding back in 2002/3 or so. But there was on "popularity" to them. Funny how I come back years later and find out there's a big bunch of 350 fans. I always have been--but had no one to share it with much. But that 116s and 7900 showed me what torque and CC's could do and I loved them too. Anyway. I'm "starting over" with my Jonnies and rooting around in here for some fresh JBweld. Good mornin'.
