Now I remember why I don't like XL2/Super2 saws....
Just got back in after going through an early mag-cased, two-trigger XL2 today. It's so old that it has a Walbro HDC carburetor and no UT# or Lot # (just a serial #). Belongs to a 'work buddy' of a good friend of mine. I don't like working on these saws, but agreed to fix this one as a favor to my friend. He was persistent.................and put it in my pickup bed TWICE one day when we were out cutting. I'd put it back in his trailer after the first time...
The damn thing was FILTHY. Working on these saws (for those that don't know) means pulling the engine out of the case, and cleaning all the saw cake (that builds up around the carb and everything else) out while it's apart. Rebuilt the carb, replaced the fuel lines, fuel filter, fuel tank vent check valve, oiler lines, and oil tank check valve. Got it all cleaned up and back together. Fired it up............and it smokes like a bug fogger (and acts like it has an air leak). That means that the auto oiler pump diaphragm is shot. Crap....
Gotta find a diaphragm (should be some on feebay....seen 'em before), get it shipped here, and then tear the damn saw apart again so I can swap it in. These saws are NOT fun to work on. Not as bad as a mini-mac, but still a PITA. I've told my friend that I will NOT work on that guy's saws anymore unless he blows the damn things out with an air compressor from time to time...
After disassembly, cleanup, and carb rebuild. Putting in new lines and check valves (duckbills). Cleaned about 1/4" of melted fuel line good from the bottom of the fuel tank.
Old chewing gum lines, munged up fuel filter, and dead carb diaphragms/gaskets.
Going back together.
All together. Air clearing out after smoking up the shop. Now to find an oiler diapragm...
Edit:
Anybody here know whether the
69242 diaphragm/plunger (# in the IPL for this early XL2) is the same as the later
12356 (and
12356A,
12356B,
12356C) diaphragm/plunger? I've only been able to find the
12356 variants on the bay (and sheesh.......they're expensive)...
