You may have to pull the large (1") welch plug and see what's going on underneath. My other 550 has the check valve, and for some unexplained reason it stuck on me last year when I was preparing the saw to take to the PNW GTG that I never managed to get to. That saw had worked fine the few times I'd used in prior, and has worked well since dismantling the carburetor and unsticking it with some carburetor cleaner.

Yours will either have the same sort of check valve, or a "capillary seal" made from sintered metal and it sounds to me like it is either plugged or blocked. Last time I checked, Bob Johnson had the 1" welch plugs, or I'm sure you could find some elsewhere just as easily.

Thanks for the advice. I'll talk to Bob Johnson about the welch plugs (for my 550, plus Randy's 790 and my Super 250) as well as about 100 other things I'm needing for the growing fleet of yellow and black in my garage. I did see those plugs, and a 'NOS McCulloch flatback carb check valve kit' listed on feebay a while ago too. IIRC, the pic of the 'kit' in question had a 1" welch plug, along with a few other bits. I'll bet the check valve got stuck (or some gunk got shook loose and plugged the capillary seal if that's what my carb has) during the bumpy trip from Iowa to Ca....

If you look at the profiles of the starter housings, the 1-40 thru 550 saws has quite a different look than the 1-70 thru SP125 saws. I think JJ has referred to the latter as "Super Series" engines before. If I'm not mistaken, the "Super Series" covers are not as deep as the others either.

Now that's interesting. I was under the mistaken impression that the 550 and Super 550 were variants of the 'super series' engines because they were 99 and 103cc (and shared the bore/stoke measurements of the 'super series' engines of those displacements). Looking at the saw, I can clearly see the 'dogleg' curve in the top profile of the cover on the 550 (which matches the 250's and such). The 'super series' covers don't have that 'dogleg'.

I remember trying to fit the cover from a 200 on my 790 a few months ago. IIRC, the profile was totaly different, and the bolt holes were in different places. I can't remember if the length or width was much different. The 790 cover was noticibly shallower than the 200 cover as you mentioned. Just curious.......are the D44/55 saws in the 'super series' engine family, or are they like a 440, with an engine that's in the same family as the 1-40/1-50/200/250/etc?

Are you going to make it to the PNW GTG next June? I hope so. I'd like to meet you in person (so far the only old saw nut from the forums that I've had the pleasure of meeting is RandyMac). I hope to see your BP-1 and 77 up and running as well. Those two 550's in your pic could get reaquainted too...:D

When talking to Bob Johnson, when rebuilding the 797, he had recommended shooting some PB blaster in through the HS hole to help break up and clean any debris in there. He was saying the PB blaster will clean without hurting the primer. Might not work, but it might too. Wont hurt.

I'll give that a shot Brian. I certainly don't want to damage the primer on that carb since it works so well, but I trust Bob Johnson's experience there. I'll pull the carb from the saw first though, as I don't want PB blaster getting into the engine. Won't lubricate things very well as it goes through methinks. Maybe I'll get lucky and not have to pull the welch plug.

I'm having trouble finding a carburetor and wase hoping one of you might have a carb that fits a pro mac 355
 
My McCulloch saws, 5-49, and 3-25.

Hi everybody. Dad used McCulloch, as did my Grandpa, so they are my favorites. I only have two left today, my 5-49, and 3-25. I have kept them because I feel like they are just a good pair that represent the McCulloch state of the art of their times. The 3-25 last made chips with me at the throttle five years ago. I really liked running this saw. I have long thought I could handle a saw, having used an 026 while climbing or from a bucket, and I even took an 084 up in the bucket with me once, but the 3-25 is a good heavy brute in it's own right. I really like these old ones. Hell, I have a 1958 refrigerator I am still using..LOL! Does anyone else really like their 3-25, or 5-49? I feel like they are benchmarks for McCulloch.

Those are grand old saws. Glad to hear you kept some McCullochs that belonged to your Dad and Grandad. Take that 5-49 up in the bucket! Make sure someone takes pics...:laugh:

You have a 1958 refrigerator eh? I'd love to have an International Harvester fridge and freezer for my shop. I know several folks online that have running IHC fridges and freezers. Talk about being built to last...

I believe the last year for those was 1954. The IHC refrigeration plant was where IHC built M1 Garand rifles for the US Army by the way. The refrigeration plant was eventualy sold to the folks that formed Whirlpool...

An IH collector near me has one as his shop beer fridge :clap:. I'd LOVE to find one...
 
I have a 3-25 that is in pretty good shape, but needs a diaphragm for the carburetor. Other than that, I think I have all of the parts needed to get it going again.

From Mike Acres site - the Titan 7 was introduced in 1990 and made in "an Italian McCulloch factory".

I'm not sure of the story behind the Titan Series saws, do they share any parts or heritage with Olympyk/Oleo-Mac????

I have a Titan 57 which aside from a lot of plastic seems like a pretty nice saw. I had to take it all the way down in order to replace the fuel and oil lines, but I like the way it runs and cuts.

Nice 3-25 with helper handle.;)
Those helper handles are kinda rare.
 
Thanks Cliff, I have 5 or 6 bars with the three hole, and one more of that style of helper handle (thanks to Bill G).

My 48" bar on the 840 also has a three hole pattern, but it is a different spread and the same old saw handle won't fit it.

If I remember correctly, that is a brand new Stihl braded 1/2" pitch chain on that one.

Mark, if you don't know, you think we do? Lots of plastic doesn't sound Oleo-Mac/Olympyk to me, but could be; could be Martains too, but I doubt it. I wish we knew more from one side or the other, but I keep hearing zero from the Oly side, and never seem to hear much from the Mac side when they started farming saws out, eg the Power Mac 1000 and the Titans.
