Not a GT, but thought I'd ask anyway...

I know it,s not a GT, but I thought maybe one of you Jake guys might be able to help me out with a bit of info.
I just picked up 2 rotary mowers for $20.00 (that's for both, not one) :smile1:
One of them is a old Jacobsen 4 blade. It's the 18" one with the 321 2 stroke engine.
I'm trying to find out what the correct gas/oil mix should be. There is nothing anywhere on the mower to indicate what it should be.
It appears to be in good shape and has pretty good compression. I'm hoping that it doesn't have anything major wrong with it, as I'd like to get it running.

So, I zipped down to Wally-Mart, got a new gas can, some 30 wt non-detergent oil (which they also specified), mixed it up, poured a bit into the tank, put in a new plug, and danged if that old girl didn't fire on the first pull
However, it wasn't running right, as it would run on choke, but when I moved the lever back to high, med, of light, it would run for a few seconds, and then cut out. As long as I kept switching back and forth to choke it would stay running. It was also blowing smoke like one of the Blue Angles jets as well.
I took a bit of a break, and then took off the air filter cover, to discover that there wasn't an element in it, and that the choke plate was COVERED in greasy dirt!
Seeing that, I decided to take off the carb, and see if I could clean it up a bit. With a LIBERAL dosing of WD40, I got all of the crud washed off, and had the carb looking not too bad. Some, if not all, of the fuel that was in it drained out as well.
I reassembled everything, and used the toe portion of one of the wifes old Knee-High stockings to cover the entire air cleaner assembly. I figure that it keep out most of the big dirt, until I can get a proper air cleaner element.
I checked the plug for fouling, filled the tank full, and once again, the old girl fired on the first pull, but THIS time, settled down and kept running on all of the settings. She was still smoking pretty bad, but after a minute or two that all went away as well.
I decided that it was time to give her a test. I have some pretty high grass/weeds in a ditch in front of the house, so I cranked the old girl up to high, and had at it. It didn't even breathe hard and was knocking down 1 Ft high grass and weeds like it was nothing. Just like I remembered my Step-Dads 4 blade Jake doing back in the mid '60s.
