MCCULLOCH The official McCulloch thread

[the 28inch mac man]

I wish you the best with that. Been looking for 3 years now in both the US and Canada. US Chrome will do them again now but only in lots of 10 of the same cylinder and only if you have them blind bored before you send them. By the time you get done you are right at $400 in each cylinder door to door, maybe a bit more with shipping to the machinist, then the US Chrome WI, then to US Chrome in New England, then back to you.

I wonder if it would be less expansive if you could have them done in bulk......

Honestly I can only blame myself with hopes of finding an operational saw used, like @Knightmax said it's a gamble , scraping noises inside are usually a good indicator of badness though. It is possible that enough people haven't handled a roached top end saw also?, my experience is vast!
@heimannm built my finest running 82cc McCulloch, it did try to escape his hands to blow up on me though! As most are well aware; he's a man of his word and persistent.
I've been having a run of bad luck with saws lately too, so maybe I'll focus more on using the ones that do run and wait for warmer weather to hang out in the shop rebuilding ones that don't.
I have a couple vehicle projects to keep me occupied for awhile right now too.
FYI I keep all my bad topends just incase things get sorted with the plating or sleeves.

Not sure what the confirmation was for "great compression " was ? But I have a different idea of what it is.

So his test for "great compression" was to hold the saw by the pull cord and it didn't pay out.....a seized piston will give the same result...

Gentlemen,did everyopne here forgeyt about our member @Vinnywv? He has a friend who has a machine shop who will bore out those 82cc cylinders & install an iron sleeve for a fraction of what U.S.Chrome wants to replate one.

And my understanding is they are not functioning as they should.

one hint of a usually good cylinder is a fixed high carb. knock on wood, every fixed high carb saw I have gotten has been in good shape chrome wise.

I have been working on building a library of gaskets with SVG files and doing test cuts on my wife's Cricut cutter with card stock (verifying correct sizing before using on gasket material). I thought I would get the fuel tank gasket and oil reservoir gaskets off of my (new to me) non running McCulloch 200 and work on building their files. It was a bear to get the fuel cover off, unfortunately the gasket was unrecoverable, if it didn't tear it was gooey and what a smell I discovered...

Looks like you have your work cut out for you, so to speak.

I told my wife that she could get me a media blaster for my birthday!

 

[edju1958]

It seems to me that the one(s) that vinny did ran fine & he even cut with them.

 

[heimannm]

I traded some messages with Vinny, one of his was O.K. and the other behaved much like the one I described.

Can you guys help me with the models of recoil/starters that will work for my newly acquired 795 please? TIA!

Any 440 740 790 797 recoil will fit a 795. Nice fined! I just got my 795L running today, and what a great saw! I adapted a sdc carb to fit it, and what a difference the sdc carb makes.

What carb was on yours before?

Nice looking saw!! I am working on a 200 right now.

 

[Duke Thieroff]

Been wanting one of these for awhile, finally found a nice one locally for a fair price. It should clean up really nice.

 

[Duke Thieroff]

Reasonable explanation as to why it won't run.....

Correct me if I'm wrong,but wasn't the Super 250 & the Super 44 pretty much the same saw at 87cc.?

You are close in thinking and the motor is the same displacement, but the Super 44A has a larger bore and shorter stroke, the Super 250 has a slightly smaller bore and longer stroke.

My saw had a flat back before the sdc. I also tried a tillotson hl, but the big bore sdc has no compairison.....
