I was planning to attend the PNW GTG but something unfortunate came up.

I did get a few photo's of the group of saws I was planning to take along. Contrary to what some guys in Wisconsin may have seen in the past, these all start very well, and run pretty well too. O.K. I haven't had a chance to put the Suer 250 into the wood yet but it sounds good anyway.

Anyone in Iowa have some big logs they need cut up next Saturday (12 June)?

L-R Super 250, 550, 55, 1-85, SP125, SP105 (from Belgian), 840
In front 1-70, MM120

what do you guys think of the pm610 and what would be a good price for a good running one? Thanks for any input.
 
thanks theres one on cl says it runs good 100$ obo its tempting, I d offer 60- 75 maybe
 
Where would you find a full wrap bar for a Super 250 and how much do they go for? My half wrap is pretty nasty and taking alot of effort to clean up, just wondering if it is worth it.

I have bought them off Ebay $18.to $20. for used ones.
$25 to $30. for new ones.
 
Newbie building a saw

As you can see I am new to this site (I hope I am posting in the right place – if not, just let me know where to go). I am even newer to rebuilding a chainsaw; but I got bit by the bug when I tore down an old PM 850 and bought a dismantled PM 800 with a melted piston. Long story short, I recently acquired a NOS cylinder and crankcase which from all measurements appears to be a PM 850 or its kin. I have decided to build my own felling and bucking saw from the various parts I have. From the late model (and from all appearances, low hour) PM 800: the crank, rod, oil pump, tank, flywheel, ignition, clutch and full wrap bar. From a Super Pro 81: the undercarriage and NOS muffler. From a PM 850: the shrouds, chain brake & starter. I’ll have to buy the “B” piston new. I have been talking to JetHot about coating the piston and muffler. Of course, they are all for it and it won’t be cheap. My questions for you guys with MAC experience: 1) Are the cylinder and crankcase matched? Or can I use my PM 800 crankcase? 2) Should I look for NOS bearings or go with those on the PM 800? 3) Should I polish the exhaust port casting? Or should I send this to somebody on this site for such? Or just forget it as this project is meant to result in a dependable working saw running 28 to 32 inch bars? 4) Any experienced comments regarding: a. muffler choice? I know it will be loud. b. ceramic coating of muffler? Goal is longevity and performance. c. piston coating by JetHot, ceramic on dome and antifriction on skirts? Goal is longevity through heat protection and less friction. 5) Other than the lack of a boot loop, any downside to SP81 undercarriage? I like the look and solid handle attachment of the SP81. I like the rear bumper arrangement on the PM 800 but the cylinder doesn’t have the necessary boss to attach the rear shroud. I know the PM 850 has a wider spacing on the bumpers (I thought about adding two more bumpers if this is an issue; I have zero experience with these AV MAC’s). For what it is worth the flat sheet bottom on the PM’s has little appeal to me. I don’t start or run my saw on concrete or pavement as so many on E-Bay look like they have, nor do I leave my saws idling on the ground. Thanks in advance for your help.

Brian, the bars for the 1-50 will work, are they nice shiney chrome?

They should look like the ones on this thing.

Yeah they look just like that. Not only do I like the look of the full wrap, but the bar I have is rusted so bad. I have spent about 45 min. using wire wheel on a grinder, razor to help scrape rubber coating, 80 grit sand paper, and bead blasting. And I am still not done. Im thinking a full wrap. Thanks for letting me know those will work.

I really like that kind of "muffler" on those older Macs. I had a saw like that once and in my inexperience traded "up" for a 610 and gave a bunch of money extra.

I may be able to stir up some logs at the farm.
Picked this one up today. Didn't even get to look at the D Eagle 80 I mentioned.

beater 250

This is my general purpose chainsaw, I have three B&C combos for it, 20" roller with 3/8" chisel, 20" hardtip 404 chipper, 30" sprocket 3/8" chisel semi skip. Changing rim sprockets is a five minute deal, I'm slowly converting eveything I can to rim sprockets.
