Question - McCulloch Pro Mac 610 Chainsaw

I was given one that will not run and the bar oil tank apparently leaks. It is in nice looking condition and am going to try and get this operational just for fun. After doing some searches I have found a fair number of threads from users complaining about the oil leaking when the auto-oiler function is on. Any one have any idea how you turn this off? I would like to confirm that issue. The no start issue I expect to be fuel related and will start with the carb. Anyone know if kits are still available for these old McCulloch saws? I know that McCulloch went into bankruptcy and the rights to the name were bought out in court. I am just curious about the parts situation.

One other question. I plan to tackle the no start issue first and the leaking oil second. Any reason I should reverse the repair process?

Additional info - I found a pdf document on the web containing an illustrated parts list for the saw. According to the document dated December 1984 there were three different carburetors that were used on this saw through that date.

A Tillotson HK 19A, a Walbro HDB-6A, and a Zama C-2S.

I can see that I will have to see which is on the saw I have and check a local shop for parts availability.

Well, I just might be hosed on this saw.

It turns out that is has a Zama carburetor with C2S on it. According to the Zama web site the Zama number for it is C2S-19-01 and it called for kit RB-18 or gasket set GND-10 both no longer listed as available by Zama.

Time to hunt for old inventory.

Some of the more diligent shops have the diaphragms separately. Kits come with gaskets that fit many similar carbs. If you can find a shop that does this, you can take the old ones in with the carb and match em up.
Couple of the older gals I know of in a couple shops been doin this for years, can find them pretty quick by looking at the numbers on the carb and knowing the kit #.
Less than 10 bucks most times and ya get to meet some really neat Senior ladies

The problem I will have with this particular carburetor is that Zama lists both the kit and gasket set for this unit only.

See http://www.zamacarb.com/pdfs/QuickKit_CR2007.pdf

I ordered a kit off ebay.
