Super 55A, running pretty good. Didn't take much. Fuel tank was missing the wick assembly so I stole it off my S44A junker. 55 came with some goofy Mac carb that is not a flatback so I stole the S44 carby for now till I can find gaskets and diaphragms. Cleaned the points and all that. Soaked the chain in oil to get it freed up and discovered the good old Mac master link setup. Still has a miss at high RPM (currently it is ungoverned!) I will look into finding new points and condensor for this thing.

Even with a dull chain it cut pretty well.

Master link, master pin, and pintail chain.

Think the previous owner had trouble getting it to run?

I saw one of those 'goofy mac' carbs on ebay recently. IIRC, it was listed as being from a D36. It did have a flat/squared bottom (compared to a Tilly HL) and didn't have a choke or a primer. Looked like it had been used with a sliding 'snuffer' choke cup like what I've seen on some 'button' choke HL's on these earlier Macs. Saw another one too. Can't remember where. Sort of looked like a cross between a chokeless HL and a later flatback mac carb.
 

Jeez you guys........................................might as well put "There's a McCulloch Super 797 on ebay right now. EVERYBODY go bid the piss out of it!!!" in a full page banner on the front of the site. Some of us found the auction on our own and bid before it passed three figures. Crikey, it's already gone past $150 with several days left.:hmm3grin2orange:
 
On my doorstep. :msp_flapper:


Jk. :D

I hope you get it, but be warned, they exhibit their own gravitational pull. Don't leave it on the proch too long or it shall be transported across the time/space continuum to be with their MI brothers...


Tell customer service they can come collect my excess inventory, but they better bring an army and pack a lunch ;).

I already unwrapped it and cut the couch in half. :D

An army of two, me and SS. :)

You're not far off. Looks to share the metering diaphragm with the flatback, but not the pumper. A search of the part numbers shows the MC-10 uses the same carby.

The carb you're looking at came out of my S44A. The S55A carb was tore apart and tossed into the airbox. It is missing parts. I've found a pump diaphragm and the gasket is still salvageable. I'll rob the metering diaphragm from one of my flatback kits and see if it all works.

I have that same carb waiting for a rebuild. Havnt even had it apart yet, it will be awhile though before I get to rebuild it. Still a long ways from worrying about the carb. In comparison to the other two flat backs I have used(primer style and standard choke style) this one seems to be a PIA. I have read about bypassing the governor, how does that work?

I couldn't just leave cpr in the dark. We all know he needs something to run all those large roller nose bars he wants.

At least it didn't have a BIN price. Doesn't it kill you to find an item that had a BIN price you would have gladly paid only to have the BIN price taken away by a 99 cent bid.

Hope you're not too mad at us/me. :buttkick:

Your mileage may vary...

Nah, I'm not mad at you knuckleheads. It'd been bid way up out of sight anyways. The only saws like that which don't go for stupid money on feebay are the ones that have goofy titles in the listing. An example here would be "MacCoulogh Supers 7-97". If it's a stupid enough title, sometimes the item slips past most searches. I've been lucky once or twice that way...............but not with something as cool as an S797. I've had the "ruined BIN" thing happen to me more than a few times. I'd see a listing with a BIN price that I may be able to swing. I check my finances (and/or get clearance from the War Department) and then hurry back to the listing..........................only to find that a bidding war has ensued (with somebody bidding .99 at first) and the auction's now far above the BIN price. Stupid-heads............:deadhorse:


That super 797 has only been up for a couple of hours and its already up to 350!!! Will be interesting to see how high it goes.

Crikey........................it's more than trippled in an hour and is still going. Almost seven days still to go...............

Have fun kids, I'm out of this one...

Need to jettison some projects to get to what I need those bars for.
