Does anyone know of a business that carries parts for vintage McCullough saws, specifically a 250 model circa 1964. We love this old brute and would hate to see it confined to the storage in the shed.
 
what kind of parts do you need? I've got one myself, an 80CC powerhouse saw if you ask me. mine, has a 34" bar, for gits and shiggles. its cool though when it comes down to the REAL thing and you gotta cut wood.
 
Bob s lawn mower repair,Maryland, New York,on A-Site but I don't remember the name.
 
Dean at Washington Hot Saws (site sponsor) has found every part I ever needed for a reasonable price for my mac projects. He ships quick also.
 
What kind of parts do you need. I ordered a recoil spring, carb kit and air filter for my 1-43 from Manufacturer's Supply about 2 years ago. Never got the Air Filter though because it was discontinued. They carry sprockets for these old macs too. I own 8 old Macs of this vintage (in varying stages of completeness) so may be able to help you out with some used parts. Oh yeah I also purchased some chainsaw bars from Bailey's that fit my old Macs pretty well. I think they were intended for bigger Husky's but they fit perfect, oil holes and all.

Randy Duncan has some of those large filters ,or did have,a while back.A little tip on those 250's.I took Mike Acres advice and changed one of my 250's to 3/8" chain .It really put some life into that old bird.
 
So what's the big advantage to 3/8" ? Chain speed is increased slightly because the 3/8" sprocket has 8 teeth as opposed to the 404's 7 teeth. Which means the 3/8" chain speed would be 1.061 times faster (.375/.404*8/7) or 6.1%. You'd have about 7.7% more cutters per inch also, but they would be taking smaller cuts.
 
I have a rim on my Mac, and plan to add an 8t .404 rim to see what it'll do. that, and I'm going to probably try a nice 9pin 3/8 if I can. might get somewhere in a hurry like that too.
 
I got my rim sprocket from a member here, and its a 250. the rim is kinda hard to find, I just got a little lucky, and I've got one on it.
 
Thanks for the links and advice!

We'll be doing some more clearing of dead trees in a few weeks after the crops that are currently blocking our various access paths have been cleared from the fields so I'll have my dad take a more closer look at the saw, but for now he recalls off hand that it just needs a new coil.

We loved using this for cutting through trunks because you'd someimes run into nails or barb wire and it just keep cutting.
 
Yep, the 250 will do that. I mean, its a pretty dang powerful machine for 6K rpm. I used a chipper chain on mine once, and threw TOOTHPICKS instead of chips with it.

3/8" chain is also lighter, meaning less weight to have to spin so it will take less time to accelerate, and will require less power from the saw just to keep the chain moving, meaning more power to rip out chips with.
 
My 250 has a nice roller tip bar and 3/8 round chisel chain. I've tried 8 and 9 pin sprockets. It pulls the 9 easily, and is faster than with the 8. 3 cuts in 10" square pine in 12 sec. My buddy has an 044 and a 440. The did it in 10 and 11 respectively. In bigger wood, say 16" round, the 250 wins easy. I also put together a nice 300 with 3/8 chain and an 8 pin rim. It beat the 250 with the 9 by .2 sec. I put new points in the 300 and set them at .018. I'll have to do that with the 250 next. If they were lighter and had antivibe, they'd be great.
 
Well the old 250 is one of Macs classics,they must have made a million of them.This,incidently ,was one of the very first saw I ever operated.When they were newly on the market.They are typical reed valve McCullochs,built like a tank.
With a little "tweeking " they will run faster than 6,000 rpm.Because there are so many,I never considered them rare or valuable,but they are durable.
Although there is no suspension system I never felt the finger tingling vibrations felt on the 10 series of saws.That could be,in part,because of the weight of the saw.
On this matter of a bad coil,I've never experiaced a faulty coil on the series of saws that used these large coils.What problems I have found have been in the primary ignition circuit.This consists of the points and condensor.I'm not saying that it isn't a bad coil but rather I've never seen one.
My 250's do not get much use because of the fact I have more powerfull saws and a multitude of them.They do however get started,periodicaly and have a cut or 2 made,then back to the shelf.
