Eccentric
Mister Wizard
Got my first big homelite last week. it is a C-71 that hadn't run in 16 years. was sitting in an old welding shop gathering dust. it was stuck, but only lightly, more like a hesitation. put some blaster in it and got a ratchet on the flywheel nut and it moved with the first pressure. guess the pull start just didn't have enough leverage. whew. next is the points, no spark there, but at least the flywheel came off easy. the carb box looks clean and bright but it's the tank that worries me. i can see the fuel pick up is embedded in a layer of goo that reminds me of the la brea tar pits. there has got to bea 1/4" of stuff in there. i can't pry the filter out of it so may do some soaking like eccentric referred to earlier. may have to pull the front of the tank off. any other ideas on this ? here's a pic of the bar and the number on it. i get the feeling it doesn't have a lot of time on it. now i have another 80cc saw to go with my l-71 mcculloch.the piston looks clean, no scoring. i want to hear this thing run.
Nice C-Series score! I'd pull the plug again and shoot some light oil down there. Even WD40 will help. Crank it a buncha times with the plug out to distribute it. The rings were probably lightly rusted to the cylinder, and the PB busted it loose. That stuff isn't much of a lubricant however. You won't wanna leave that ring set dry any longer.
The points are probably rusty/dirty from sitting in the same damp air that made the rings stick. Since you've already got the flywheel off, you should service those bad boys. Make sure the condensor is well grounded where it attaches to the saw as well. As for your tank, I have a thought...
Looking at the pics, it looks like somebody replaced the tank cover. The paint's not even close to the 'fade' of the rest of the saw. I see what looks like black sealant of some kind on the gasket. Maybe they poured a buncha sealant in the tank as well. That could be your 'tar pit' on the bottom (if it's not just stale gas). I think you're gonna have to pull the cover off in any case. Tank gaskets are available on feebay. Be careful with those thin slotted head screws however...
