Which model saw is this?

[kgw51gmc]

I need to do carb rebuild and maybe some other TLC work on THREE Of this saw.    I have 2 and my granddad has 1 that is IDENTICAL but says "Remington" on it.     
If I can ID this saw in the right forum I can learn something about the carb rebuild, I'm sure I can't just buy a $10 carb and go.   I don't see any forums that match up to this model.

Here is tag info;   MOdel 105074
                          SErial No   780860057     12" bar, Homelite XL        

I may try pics when I figure out how.  (My Google storage is full and have to climb that hurdle before I can load pics).

You'll have to get the carbs off of them and identify them to order carb kits. More than likely a Walbro.

Here's everything on the carburetor:
1 21-109

H HDC 48A
L 2/78

That's the approximate postion of the numbering also. All right on the carburetor. What's the right kit for this one? Any tips on rebuilding/cleaning this carb vs other ones? I like replacing carbs more than rebuilding, seems like I can not get any luck when rebuilding a carb on a saw/trimmer/mower. But on a truck/car/farm tractor it always works......

Thanks.
