Help with McCulloch 3-10 DSP

[kondoge]

I’m new around here and am needing some help. I found a forgotten about Mac 3-10 DSP it needs some tlc. What I need to know is what kind of fuel mixture should I use if I only have 2T oil or stihl 50:1. And also if any other things I should check for.

I run all my vintage McCullochs at 32:1 ratio with FD rated oil and no problems. I know this isn't an oil thread but I use Echo Red Armor and it's great oil.

First thing I would is try to remove the muffler to have a look at the piston to make sure it's not scored up.
