Same here...if I'm ever in that part of the country I'll be dragging my wife to the chainsaw museum, haha.

Nice job on the cutaway saw, I like that even the carb is cutaway to show the diaphragms.
 
one year ago next week, I got this saw in a 3 saw deal. was going to paint it but couldn't find any decals. contacted the guy on ebay who did the really nice decal kits for my SP70 and 10-10S restos but he said he couldn't do them for this saw unless I sent him the parts with good decals to go off of. of course, I didn't have any parts with good decals. last week I was browsing and found these on his site. arrived today. I think I may have just enough of the yellow left from the 10-10S to do this one. back on my bench, I guess. :sweet:

Cutaway looks good, Mark.

With our local circumstances making national news, I am sure you guys will forgive me for asking an off-brand question or two. A friend of mine had his farm shop completely flooded leaving mud filled equipment, including several chainsaws. His brother asked me if I would see if I could recover a MS290. It was packed in mud. Fortunately, the piston was covering the exhaust port, and the air filter seemed to have filtered the silt out of the water that filled the chamber. Both the gas tank and the oil tank were full of water. Anyway, I have cleaned it up the best I can short of a soak or a pressure washing. I have it sitting to dry with the plug out, the air filter off, and the muffler off. I don't have the tools or knowledge to take it completely apart. Any advice on any additional work or method to dry it? Any advice on pre-start measures?

Thanks,
Ron
 
Sorry to hear about the flooded saw... unfortunately I can't see much chances that vital components like main bearings could have avoided getting silt / dirt in them, and it would require a complete disassembly.
However, if it was me in a dire situation with a flooded saw, I would fill and drain the fuel tank, oil tank, and crankcase with diesel, kerosene or gas a few times to hopefully flush out any junk, and then try running the saw.
 
Is anyone able to ID these saws from these pics? Especially the one in the back with the black air filter cover?

Random listing on Facebook Marketplace, just says "old McCulloch saws and parts"...

No price in the ad, could be junk or a hidden gem, it's about an hour drive from my house.

If muddy water got in the saw, the bearings now have silt fines in them. Will it run without a complete tear down and cleaning? Yes. Will it run long term without it. No sadly.

Ive rebuilt 2 ms290 saws. They are quite simple compared to mccullochs. You can have the whole top cylinder off in a matter of 4 screws. From there it would likely be easy to flush it all out and pretty thoroughly done. Put it back on tighten the 4 scews and fire it up. The only tough part for them is the carburetor and again its not that hard but it may be the hardest part. Take you a few hrs and itll be done. The few hrs is just because youve never messed with it before. The next time itll take no time at all.

if it got sand silt in the crank bearings, not sure a flush would get all that out. but not sure it's worth putting new bearings in either.
 
I picked up these saws and parts today from a nice fellow that decides he was done tinkering with them. I got all this absolutely free.
I'm going to have to do an inventory and assessment, but they're mostly in rough shape, basically salvage saws.
The most complete saw is an old 450. But....the engine won't turn over completely, only about 3/4 rotation and then something is locking up solid a bit before TDC.
I may or may not be able to make a running saw, but if nothing else I have a trove of parts, some neat bars, a 404 and an even bigger chain, etc.
That 4-30 is an absolute monster, much bigger than it looks in the picture.
