Husqvarna 2100 bar oil in fuel tank?

[scotiansaw]

Hello everyone. I recently purchased a husqvarna 2100 for $100 and have been slowly restoring it to its glory. Saw was running great for a day or so, then began to randomly bog out and stall. After taking apart the carburetor (just rebuilt and cleaned) it looked like pure oil inside. After draining out the fuel the mixed fuel poured out, then slowly about 70ml of black oil came out from the oil tank. I drained the old fuel out prior to using but never cleaned the tank.

My question is, could this be bar oil leaking from the oil tank into the fuel tank? They 2100 has integral case tanks for both, however it does not seem to have a seal for between the tanks. Could it just be old oil from the gas in the tank from sitting for years? Fuel line was disintegrated. Running 32:1 for milling.

I appreciate the help.

I am having a similar symptom with my 024 Stihl. Looks like some oil coming out the muffler. After tearing it down to
the case and changing the seals and lines, I've got it down to a carb issue, too much fuel. It idles and revs well and has 165 compression but bogs a little at full throttle. I'll deal with that next. I'm no expert but that's my $.02!
BTW I have three 2100cd parts saws I am hoping to make at least one good one out of someday!
