Title: McCulloch Titan 70
Post by: Al Smith on July 15, 2011, 01:58:56 pm
This is kind of an interesting saw .According to McBob and others this thing was made by McCulloch in Italy in a factory they owned .

70 cc ,vertical cylinder  made around 1990 .It's in real good shape and handles the 24" bar it came with real good .

In comparrison to say the Mac 700 it doesn't quite have the grunt but has the speed of a Stihl so it about evens out .Fact it's not much different if any from a Stihl 044 powerwise .

Dumb me couldn't figure out why in the world the danged thing would sputter out after a prime because the thing had sat about 4 years .So I rebuilt the carb ,nice but not it .Fuel lines gone .Shoulda thought of that in the first place .

This model sitting on the tail gate of my Ranger is the only one I've ever seen in my lifetime  except pictures on flea bay .

Posted same pic 2 times.  ;)

A couple posts under the shrouding .This is the power side .The thing runs an outboard clutch like Stihl with evidently a crankshaft driven center mount oil pump .The screw  right center below the clutch is the adjustment .

Top side ,center combustion chamber decomp .The rubber gizmo on the spark plug boot completely seals off the top shrounding so the fan blows full force over the cylinder .Must work ,this thing is clean as a pin and I have never blown out the dust .

It's got a pretty good sized air filter all things considered which seems to work fine .The gas cap is some model of Husqvarna which I had to slightly modify to work .Hmm gas cap mod ,who knew . ;D

Actually by brother in law gave me this thing along with a half dozen others .One was what got turned into the piped mini Mac .

He complained this Titan was hard to start ,well with a **** fuel line that makes sense it would start hard .

Ha good old Dave used to go with us about 30 years ago when myself and my dad who was about my age now did a lot of cutting .The old man and I ran Mac PM 610's ,his pepped a tad bit .We always outran my brother in law which annoyed him .He showed up every week with a different saw but to no avail .Once he got his hot little hands on a souped 10-10 Mac which he ran on 50 to 1 with AV gas and 10 percent nitro .It ran alright just not too long .Grenaded a piston after about an hour .

Al just letting you know a lot of titan 70 NOS cylinders and pistons popping up on feebay.
Title: Re: McCulloch Titan 70
Post by: Al Smith on January 21, 2013, 04:26:12 pm
I saw that myself . Like I said I've seen exactly one of them ,the one I own .I still think it was about a sink or swim last ditch effort on McCullochs part because by 1990 they had just about lost the war .

Just goes to show you if you don't take care of business you  won't have a business to take care of .They didn't and now they don't .

Is your 70 a runner I could test out sometime?
Title: Re: McCulloch Titan 70
Post by: Al Smith on January 21, 2013, 05:51:16 pm
It runs okay .I had thought it had about as much go as an 044 but it doesn't .Not bad but no cookie cutter .

I really am doing the thing injustace by not running it any more than I do .I have my favorites but any of them do a little better if they get a run now and again .

Kind of odd ,it's bone stock .I don't think I have any others except the large Macs and the 2100 Homey  that hasn't had at least an opened up muffler .This thing is quiet which is totally out of sorts  for one of the  saws I own .Because of it's rarity it's doubtfull I'll ever do a thing to it  and leave it as it is .

Al was I was looking around and there was NOS 3 top ends FS.   Has a good looking piston it it.

Post by: Al Smith on September 07, 2013, 08:45:19 pm
They could be the exact saw as the Titan 70 for all I know .Mikes sites gives the displacement at 70 cc same as the Titan .

Those   saws would have to be rare because according to Mikes info they list first year as 1998 which I think is when McCulloch circled the drain .Gone forever as we once knew it .

I can't help but wonder why in the world that guy in the vid hung a 36" bar on it . ???

Post by: brokenbudget on September 08, 2013, 07:00:05 am
mike's site is wrong on that date. they showed up about a year later then the titan 50-57's hit the shelves. that was about late 1989-90. there wasn't much interest in them around here. there was nothing wrong with them, just cost perspective. why buy a $460 70cc saw when the pm700 was selling for just over $200 at the time. plus the reputation of the 700 didn't help the titan much. around here, if you ask an owner, they'll tell you it never needs to be worked on and is the most reliable piece of equipment they own. if you ask a mechanic, they'll tell you it was one of their best money making tools to come through the door :D we never sold any while I was at bentons. never even been into one except to repair a pull cord. and that's all the customer brought in :( and only ran one for about an hour. seemed to like being a touch richer on the hi than others.
gotta say, never have seen a pm72 8) not here in the americas' i'd imagine?

Post by: Al Smith on September 08, 2013, 07:26:39 am
Well quite frankly in owning both a 700 and a Titan 70 I'd take the 700 .The Titan 70 runs at higher RPMS but it doesn't have the low end pulling power of the old horizontal cylinder 700 .

Some of the 10-10s' vibrated so much after about 5 minutes your hands go numb .Oddly I never had that problem with a 700 for some reason .My only complaint if ran hard it hot weather some times the 700 didn't want to start so well after a refuel .How the Titan 70 would do I have no idea because I haven't used mine that much .

It'sa nice enough saw but I have better ones colored orange and white that do a better job so it's more or less a shelf queen .

Love my 700 but as you say run hard in hot weather hard to restart Run it totally dry and it becomes a real PITA it would not restart till the day after. But now 2 or 3 pulls from cold away she goes and now the first signs of running out of fuel I shut her down
Title: Re: McCulloch Titan 70
Post by: Al Smith on September 08, 2013, 08:45:45 am
Well truth be known you really don't want to run any of them out of fuel if you can help it .You can dump the fuel in the tank and let them idle out if you want to store them with no problem .You'd be surprised how long a saw can idle with just what little amount is in the carb .

Oh say a few months ago I finally found the proper fuel cap for it .Good ole Bryce had one .I had used a modified Husqvarna cap up until  then .Now it's completely McCulloch including the chain which is hanging on a nail some place .I haven't used the 24" it came with nor that chain since I got it .Then too I doubt I've put a half hours run time on it .

If it were all beat up I'd mod it .However since it's in such nice  shape it will remain stock.Some things it's just better that way as I see it .

Some day I would like to make a cut or 2 with it when time allows for us both.  Just to see for myself how they were.

 ;D I'll have to see if I can get it started first .I haven't used it in a couple of years and quite honestly really not too many of the others .

I'm going to work 8 hour days for a while instead of 12's so maybe I can get caught up .More dead trees,ash ya know plus a few hickorys for some unknown reason.First however is a small mountain of firewood already cut which should have been split and stacked 3-4 years ago .Mostly oak but danged if it doesn't have some rot .Oh well ya snooze ya lose .

I think they are pretty rare to find .Most likely by the time they came on the market McCulloch was already in the death spiral .I think the auction of the tooling etc was in '98 .That was it,no more ,just a blurb in history .

Looking a little harder for a 70 72 in 2018. Just because I want to check one out on the inside.   Video of 72 insides in its thread here too.

Saving info

Al Smith shared on his. From what little I've used it the thing seems to have about as much power as any other stock 70 cc saw such as a Stihl 038 mag or 044 . Just seems funny a Mac that sounds like a Stihl .The thing has a decomp,good anti vib and a good oiler .Handles a 24" bar buried in red oak .I have no doubt it could handle a 32 for that matter .
