You guys. I was down to 10 saws in Febuary. All Homelites except I big Echo. Now I'm back up to over 20 with a couple of nice Macs. A 550 and a Mac 15. Today my best friend's son sent me a message. A 70's Mac 6. Was cleaned and put up 20 years ago. Cylinder was oiled when put away. Ten bucks. I told him grab it, I'll give you 20. Alas, it was sold. Hope one of you guys got it. Manassas VA. Red and Yellow seem to go together on the shelf.


Yes they do,mine get along just fine never fight or argue.DSC01202.JPG
 
The PM850 Brian built, he used valve lapping to smooth out the mating surfaces. You could pull the saw over with the valve closed, wait a few seconds, push it in and it would go pssst. None of my saws will hold compression that like that though they will pass a pressure test.

If you just want to do a pressure test maybe you can find a threaded brass plug.

One of the saws symptoms is low power..... my two 10-10s have more balls.
This isnt the treaded in style dsp, it is operated with a lever system off of the kill switch. It is a tapered pin that fits into a corresponding hole in the cylinder. Cannot access it without pulling the airbox/fueltank.
 
Picture is worth 1000 words.

A leaking DSP valve shouldn't be a longevity problem - might have a slight performance difference. I have run an 800 or two with loose valves and once or twice after a valve had fallen out completely.

Brian and I did a little cutting today.

Maple snag #1 felled with 800:

Borrowed Brian's fresh SP125C to fall Maple snag #2 (Nice runner BTW):

Poison oak and poison ivy covered almost everything. Managed to get a little on my face - didn't think to wash my face with Dawn when I was washing my hands and arms. Live and learn.

PS to Brian - little saw is okay just like you predicted.


Here is some more pictures from today of Ron cutting down that maple snag #2 with my SP125C.

Glad little saw is alright. I have 2 10-10s that will go rich while on there side. Not sure what the cause is for this but mine are not as bad as yours but still rich. You could lean the high up a little and it will quit this but I prefer my saws a little rich on top and just leave them alone. Don't really hurt anything, just a little annoying.

It more than likely has some carbon buildup on the mating surfaces where the pin fits into the hole in the cylinder. I bet a good cleaning will take care of your problem.

Hi All,I just picked up a Mac Flying Goose,unfortunately it's seized.I noticed on Mike Acres'site that there were two models of the Flying Goose - a 35 & a 39.I'd like to know if parts on these two models are interchangeable (they're both a 54 cc saw),& also if it's even worth my time & effort to try to bring the seized one back to life.How do I "unseize"it?I dumped a bunch of PB Blaster into the cylinder & let it sit overnight.The result was after I used a sledge handle with a hammer hitting it on the flywheel was a broken fin.That engine s set tight.
I found another Flying Goose that looks pretty much complete & it's supposed to have compression.I'm waiting to hear back if it has spark.

On the 7-10 - best way I know it to remove the tank, not really a big job and the greatest risk is you will need to replace the gasket between the tank and the insulator.

There are lots of common parts between the 33/35/39 saws and some subtle differences. Depending on where the piston is stopped, it may be possible to modify a spark plug or compression tester fitting to accept a grease zerk and pump the cylinder full of grease. Since most hand operated grease guns will generate 2,000 PSI or more, that will normally break the piston free but only if it is above the ports.

It may be the best option is to find another project saw, there where millions of those made and you can often find them for very low $$.

As many of you know, here in the Midwest most every town has a local festival day or days as an excuse to have a parade, bring in some outside vendors, shoot off fireworks, and maybe set up an outdoor beer garden or two. Yesterday was "Watermelon Day" here, we don't grow watermelons around here but the city does buy watermelons for everyone to enjoy...

Since construction was not started on my new project yet, I thought it would be good to put up my own little display since I had indicated to earlier requests for use of my lot that it would not be available this day.

Only a few folks stopped to look, one lady complained repeatedly that there was no place for the beer garden or the band on Saturday night, but at least one guy promised to send a saw my way for the museum.

Finished bucking three trees today that Ron fell and we both bucked Saturday. Sense they were not that big I thought I would give my old PM610 and one of my Pro Mac 10-10 a workout. All went well except the last tree. It was covered with vines, big vines and was a pain to get into to buck. At one point I was trying to cut some of the big vines off the tree and somehow this limb got in my chain and it swatted me in the face, then would get loose from the chain and come back and swat me again, then back into the chain, swat me again and then get loose and swat me again in the face each time. This happened several times before the chain stopped and I got it back away from that branch. That thing slapped the heck out of my face, several times. I thought I would just hit it at the base and cut it off and it caught my chain, that needed tighten at the time and yanked it off the bar. Needless to say I was madd and said a few words I shouldn't have. I was using the 610, so I got the 10-10 out and cut it off, then called it a few things I shouldn't have, then took a break and cooled off. All in all a good day of cutting. Great saws to cut with.

Well Mark, sorry for the lack of love in your hometown but you'll be a rockstar at Baraboo in a couple of days!!!! I'll definitely be up for a road trip when you get the new place up and going.

Mark, thanks for the pics and thanks for the tip of fitting a zerk fitting to pump grease into a cylinder. I have a C71 that was running when put away. A friend gave me 7 of her dads old saws and the C71 is the only one that won't pull over. I think I pulled the muffler and the piston was at the top of the stroke. Gonna give it a try.

I think Al Smith may have had one that pulled the cylinder base bolts out. I might be worth at least loosening the bolts on the bottom end to make sure you don't do that if excessive pressure is required. I'm not familiar with a C71.
 
Here is another one for the haters to hate. As far as I know, I have all of the 600 Series saws except the Super PM 610 and the mysterious 645...it is listed in some IPL's but without a model number as though it didn't really exist.

610, 605, 650, 655, Eager Beaver 3.7, Timber Bear, PM5700, SE3420, SE3720, and the Wards Power Kraft TMY240868

And oh yeah, the 690 too.

Do you have the brown version of the Timberbear? That's something that I've actually seen, the others not. But if I ever find any, I'll make sure to hold them ransom, I mean, let you know ;)
 
I haven't seen one of the brown colored Timber Bear models in person, the photos I've seen don't really make it clear if they were actually brown or just discolored plastic.

That brings up another interesting story about the one in a million saws that were painted gold. I don't remember if the boxes were marked as such, or if there were just (supposedly) put in boxes and sent out. Some searching in this thread might provide some additional clues. I also seem to recall that a poorly painted gold saw or saws had/were popping up on e-Bay as the one in a million models.
