My dad has owned a Homelite Super 2 16" saw for about 25 years. Between the two of us, we've cut numerous cords of wood (especially when my dad got those two timber permits for National Forest land in the early-mid 90s). It has always been a reliable and strong little saw, handily cutting anything up to the limits of the 16" bar (I've cut downed trees up to 20+ inches by making two cuts, one from each side). There have been times where the saw didn't stop running except to add fuel and oil from the morning till last light. We've cleared storm damaged trees and cut firewood for an entire winter. Needless to say, we've run it to the limits of its supposed duty cycle and then some.
Anyway, last time I was down to visit my folks, he commented how it would start, but only run for a few seconds, then not run for a bit. He said he changed the sparkplug, but it didn't improved. I figured it had a kink in the line or something preventing fuel delivery (ran strong when it did run, so not spark-related). I brought it home with me and tore it down.
The first thing I noticed was the air filter was gummed up and appeared to be dissolving. Into the trash with that! The fuel line was in good shape, so I left it alone, but some reading indicated the duckbill valve on the tank could cause the same symptom. That was fine, so I left it alone. I decided to change the fuel filter not knowing if that had ever been done. I figure if it's clogged, it would allow fuel to soak through, powering the saw for a few seconds at a time. I changed that out.
I can't find a new filter locally, so I got a block-shaped filter from a nearby hardware store and cut it to fit. It's thicker, but that should help it stay in place since there's no clip to hold it.
First test run, it runs, but stumbles coming off idle and doesn't idle long without stalling. Still, it runs now and restarts when it does stall.
But...
It leaks bar oil like a sieve. The hoses that attached to the oiler pump (automatic oiling) are softening and gooey and apparently leaking oil at the nipples (hate when that happens). Rather than trying to find new hose, I just trimmed the gooey part off and pulled a bit more hose out of the tank (no tank fittings, just an interference fit). That seemed to work, no more leaks.
Back together, time to tune the carb...
After a few minutes fiddling with the idle screw, H&L adjustments, and so on, it now fires right up, idles strong and smooth, and runs up through the revs without any hiccups. To test, I cut up an old 3" cedar limb I had leaning against the fence. It did a fine job making 1" slices and copious amounts of wood chips. The final test was to see how it starts cold.
I left it in my basement all night to cool off (where it would certainly get nice and cool). At 11am, I took it outside, set the choke to "full", and pulled the cord. It coughed once. I set the choke to the mid setting and it fired right up on the 2nd pull. I revved it a few times, nice and smooth. After letting it idle for 20-30 seconds, I opened the choke completely. It continued to idle fine and revved smoothly all the way up to max. It runs like a brand new saw.
Stupid Homelite trash won't even last a season.
