Old XL-12 problem solved

I put a diaphragm kit in it today. A nearby Amish owned Stihl dealer had one. I also found a Walbro service manual and OP manual on line. Turns out there is a setting for the inlet needle where it connects to the lower diaphragm. It started on the first tug and I hardly had to do any adjusting from the preliminary setting. Ran like the proverbial bat. Lo needle open 1-3/4 turns, Hi 1-1/4, idle speed 3/5 turn after contacting lever.
 

Run non-ethanol gas and a decent oil and it will last forever. Maybe not "state of the art", but with a good sharp chain and some basic care it will cut with anything you can buy at a big box store and most of what you can get at a saw shop.
 
XL-12, The twelve pound chain saw, Homelite's done it again! That saw came out in 1963 and I remember it being heavily advertised on TV. One of many old advertising jingles from TV as a kid.
 
Dad bought one back in the mid-sixties sometime. Colored blue, manual oiler, no muffler, just an exhaust deflector. Sawed a lot of wood with it till I seized it up 25 years later. My fault, didn't keep the cooling fins clean. I threw it away but now I wish I would have kept it. As much as I like ethanol, I wouldn't run an alcohol fuel in a saw that old. The diaphragm will turn to goo if alcohol touches it for long.
