Old McCullochs
« on: December 28, 2020, 02:19:10 AM »
Pretty much sorted through all the saws I came across that I posted. Some are just parts saws but some are pretty cool. This one here,1960 vintage, a D45 McCulloch is one. Itís basically the same as the 250ís, 80cc. This one here is so clean. All I could see wrong with it was the broken shaft on the starter dog. Seems it got parked and never fixed. There are 5 saws that interchange parts in the batch I got. I-43, Two Super 250ís, One 250, a partial 550, and this D-45. I took starter parts from the no spark Super 250 and got it fixed up. Usually these saws have a thick build up of caked on time hardened crap but this one is clean. Nothing to speak of. The fuel tank has what looks like a couple ounces of oil in it though from the gas evaporating out but I look at that as a positive, no rust or corrosion in there. The next step will be interesting!

I think the only way to kill an iron cylinder reed valve Mac is to straight gas it .I've never seen a D45 model .
I'd well imagine since it had oil in the gas tank it was ran on motor oil for mix oil .I'd also guess if you tore down the engine it would be clean as a pin perhaps shedding some light on the urban legion that heavy mix can cause a lean  burn .

Thereís a few different models of this vintage that are similar, D45, I43, 250, Super 250, 550. The group of 5 saws should be able to keep a couple running :laugh:. The Super 250 has the same bore but a longer throw. The old IELís are the coolest of this bunch.

The engine on the super 44A i think is what morphed into the MC 10 kart engine according to some .I have a super 44 A which has a removable cylinder head . Plus two or three without removable heads on other saws .This series of engines in the Mac reed valve engines are my favorite .In good tune these things will surprise you .

It is! And itís alive!! Will put a video up later. Started right up on fuel down the carb but wouldnít pull fuel. Pulled the carb and gently disassembled and managed to save the diaphram and pump diaphram. Pretty oily in there. Inlet needle was stuck with thick like oil. Everything cleaned up nice. Though I think it will need a carb kit as it seems to put too much fuel out. 
Even the manual oiler works great. Clutch almost no wear.

--pull the baffle plates then they really get loud .A Mac reeder does real well on a nearly no back pressure exhaust but they will make dogs howl and wake the dead . Problem is if you do that you really have to richen up the low speed jet to the point it will blow black smoke at idle like it's burning soft coal or pine knots and load up on throttle up .It will stutter and flutter a tad bit but then all that fuel turns into power after it clears it's throat .

Thanks for these tidbits of info. Much appreciated! It goes a long way for setting things up. I have quite a bit of mechanical ability but haven't dove in to these 2 cycle things to this extent.

Yup, it's LOUD :D Careful blipping the throttle with the bar and chain removed, I had a clutch go awol doing that. I dug a shoe out of the shop wall, never did find the springs.

I spun a clutch loose on a Mac 650 gear drive that shot down my driveway, reduction gear and all and never tossed the clutch out .

Thanks for that advice. The clutch wasnít on the saw for that video. I put the cover on to make it look purdy for the video. I had that thought in my mind seeing it could quite easily get put in to orbit.

Welcome to the forum! Pretty cool old saws. There's about 4 or 5 different model numbers that interchange parts from what I see in  mine
