It's looking like I might have a "spare" igntion from my 1-51 if you need any parts. I dunno if they work, but you're welcome to them.

Quick question: I want to paint the recoil cover black, and the recoil starter housing yellow, as part of restoring two old saws. Is there a way to disassemble the recoil housing with the spring (i.e. loosen the center nut of the recoil 'winder') without having the recoil spring unravel into a mess? I just want to clean some of the gunk there also, but if it means unraveling the spring, I might not want to do it after all. Cheers!
When you disassemble the recoil ,slip a small screw driver under the pulley while removing it to keep the spring from popping up. The spring will stay in its pocket.
I thank you very much & I'll let you know what I find.I plan on popping the flywheel today if I have the time.It may just be dirty & improperly gapped points.
After a month or so of them soaking in Dawn, I finally pulled out and washed the rest of my Mac parts. The 1-51 block will get oiled and packed away with the rest of the saw, and the other bits will get sandblasted and repainted when I tackle my 1-43. Note: the coil wasn't soaked for that long, I just cleaned it when I was scrubbing the rest of the parts.
I did have the time today to get at pulling the flywheel & cleaning the points,regapping them,& putting in another condenser.I never saw such a dirty saw under the flywheel as this one.Yet under the coil & around the fins it was clean as a whistle.I put it back together,gave it a prime & I have a very nice running 450.The automatic oiler even works! That surprises me because whoever had the saw was using old used motor oil for the bar & chain.I pulled the cover off the oil tank & mopped out all that dirty old oil & put in clean bar & chain oil.Something else that surprised me is the saw has 3/8 chain on it.Here's a pic of what it looked like under the flywheel before I cleaned it.

I have a fair few front tank saws now. Most were not running. The ignition system has been functional in every one of them (and the oilers have all worked in the ones I have got running). The ignition side of things seems pretty robust (once you clean the crud out).I was about to bet you would get the 450 to spark and then I saw your post. Was the condenser dead or did you just swap it out in case?

all i done with this saw was fresh fuel after a spray down with inox and wipes it all off nice n clean. Lite blow out with compressor, exhaust port was pretty clean, same old plug still has strong spark.. everything works. Started after a dozen or so pulls. Ive used it once but dont plan on cutting more with it. Will start it every now n then.. awesome old saw one of best sounding thats for sure!.. Jack

Every "non-running" McCulloch I have bought that hasn't had something pulled off it has been the same. I prime them to save cranking them dry, but they pretty much just go. About 75% of the ones which come without carbs have leaky crank seals though. I have a good look at all fuel tanks too. I have ended up pulling the front off of all but one of my front tank saws.

Is this normal, that the sprocket and clutch drum is like one piece, or did this somehow merge/weld? Just haven't seen this before, and of course a waste of material to have to replace the entire drum when changing the sprocket...
That's normal for .354 drums.

What bar mount pattern does the 450 have?Since it's 90cc I think it could handle a 34 in.bar.

I had no idea, but thanks for that piece of info.
If it's a front tank, D196. I've got a 32 inch, 3/8 x 0.063 oregon bar someone modded to fit on those saws I'd cut loose if you need it. I've got too many bars or not enough saws...
Any large fram mac bar should fit. 250, 200, 300, 125, bar will mount up.
Same large mount of other large Mac's from early -late 60's onwards - 440,550,650,740,790,795,797,890,895,CP/SP125's etc
Not enough saws...
Since I'd moved the pistons to the new shop, I thought I'd better move the rings over too. Sadly, no pleasant surprise cache of popular rings I'd forgotten about. On the plus side, most of the pistons were complete "piston kits" that include rings and bearings so most of these will be available for projects that come through.
