550 at 99cc's, Super 550 at 103cc's

I already know that not what i asked. I'm asking about power increase like 250 to super 250 but 550 to super 550... The super 250 blows away the regular 250 in power. So...... is the super 550 the same?
 
Big haul today. Now 125 saws in my garage .. 30 runners

You did ask that wise guy, with 4 cc's more of coarse there will be more power.
Noticable like the 250's i don't know. I guess you'll have to buy one of each and find out.

Your misinterpreting my question Lee. I'm not getting testy or anything so don't read into it as such. I asked about power increase not displacement differences.

The super 250 has much more power than the regular 250. Early examples at 80cc , later ones at 87cc but beside the point. Not talking about cc's but power you can feel in your hands like the super 250.

Night and day difference between the two and with extra porting apparently. So again is the super 550 the same? I can't get any more clear in my question. Or lets say when you squeeze the trigger of the super 550 is there a lot more power over the regular 550 you can feel in your hands like the super 250 over the regular 250? You see what im saying?

I recently got a nice 550 but apart on the bench getting new seals and gaskets. I learned my lesson with old saws. From here on out every saw I buy is going to get disassembled with new seals and gaskets and a carb rebuild. Then i know when i pull that rope it will run and run like it should. All of my saws have to run or i cant justify owning it...

I collect Mcculloch chainsaws of all sizes and shapes until the J.F. generation. No pictures just a lot of saws. Mini-Macs - 125s, any of them. Do not find many around here but when I do I usually try and buy them. Most of my smaller Stihls, Pioneers and Homelites will go away soon to make more room for Mccullochs.

Had a good run of luck finding 1-10 and 10-10 series saws early this year and then no more Macs to be found again. It gives me something to look for.
I have 2 mac 10-10 Automatics looking for a good home. Neither runs. Interested? Near Huntington WVa.IMG_1045.JPG
 
Well as far as the super 550 vs regular, I guess it would be like comparing a 740 to a 790 unless the super 550 has different porting. Maybe Mark or somebody could tell you if they felt a difference. You would probably have to run them side by side I would guess.
 
If I picked up a couple 250 saws without looking at them and ran them I would know which one was the super without a doubt. I'm asking the same thing about the 550 if I ran a few of those without knowing what I had would i notice that I was running a super 550 instead of a regular because of a major power increase.

Just as some say the super 797 really is not much different than a regular 797. Is the 550 the same way? Or is it more like the super 250 and there is a major noticeable power increase? Or in other words does super really mean super in the case of the 550 unlike the 797?
 
In the case of a 797, a super 797 has less power than the standard 797. Experienced folks say thi s is due to the super 797 having the SDC which is smaller. So super doesn't always equate to better or more.
 
Thats interesting Mark. My S250 totally blows away my two regular 250 saws. It is a night and day difference. The S250 is really strong and peppy. Like i said you know your runnng one without knowing what it is because of the big difference. Disappointing about the 550. Was hoping to hear otherwise but oh well. Im anxious to get my 550 together and running to see how she runs. 99cc should be strong. My 740 is very strong so ill compare it against that and see if there is any notable difference.
 
Mark is right. My fresh 250 spanked his tired S250 in Kentucky. I know if his was fresh it would be the other way around. 4cc difference around 100 cc is probably minute in feel.

I believe the super 797 also has thick rings were the regular 797 has thin Rings. Thin ring saws seem to have more power to me anyway comparing them against thick rings. They were designed to run at higher rpms. Also maybe the lack of a boost port could have something to do with it. But I think I've heard some of the supers do have a boost port but I don't know for sure I don't own one. I haven't run my 797 really at all and i have had it awhile.

I recently got a SP125C and love that saw. Very comfortable and really easy to work on. One of the easiest saws i have torn down and replaced gaskets and seals in so far. Ill have to take it and the 797 in the woods and compare the two. I hear the 797 has more grunt so ill see. The 125 is pretty light even with a 36" hard nose bar. I could tote that around all day easily.

Don't see too many 797's but 125 saws seem to be common. I want a regular 125 that can be bored out unlike the C model. Seems every chrome plated cylinder saw i get has quite a bit of chrome worn off but doesn't seem to affect power at all. They still have great compression and run fine.
 
I mentioned to an old sawyer who runs a local saw mill that I was interested in old McCulloch saws just as a casual hobby sort of thing. He looked at me kind of dumb struck and asked why I'd want to fool with saws that were hard to start and didn't want to run when they got hot. Honestly, I haven't run the few running saws I have that much. Do the McCullochs have such a reputation? I noticed he had mostly Stihls and just one old Homelite.
 
My old McCulloch 200 was certainly like that, some days I would refuel it while running to avoid any complications getting it started again.

Knowing what I know today I would put a carburetor kit in it and fix the choke linkage so it would close fully and be done with it.

Some of the old front tank saws were bad about boiling the fuel and being hard to restart when hot.

Mark.
