Blue Homelite XL-12  I acquired about 10 years ago. It has  decent compression although piston and rings show signs of hard use. I don't know what was in the tank, it sure didn't look or smell like anything that would burn in a saw. Carb is in surprisingly good shape so it got a kit, fuel line and a filter, that carb was a bit of a bugger to install. It will start and run for a minute on choke, I suspect the crank seals are shot. Going back on the shelf for the time being, too many more pressing tasks. Next project is a Super 2 which will likely wait until winter.

If it's a regular manual oiler only XL-12 (no auto oiler pump, and has the oil fill at the rear of the saw) then it uses SKF 6119 or National/Timken 353747 seals on both sides.  Easy to get from an auto parts or bearing house.

Auto oiler versions (AND those manual-only saws with the oil fill up by the top handlebar bracket) use a proprietary seal (Homelite 58308) on the PTO side.

 Lightweight " low hour"  trimmer , non-running / engine will start only choke on and then run for a short period of time.
= fuel lines rotted.

I have had 6 of these. 

From my experience you have an air leak or carb trouble. For air leak look at the missing back cover?

Your kidding right.    That is just a big hole looking at the crank shaft.

There's a big black plastic cup that fits in the rear of the crankcase for crankcase pressure integrity. It is not in the picture? There a black metal ring that fits over the plastic cover to assure it seals all around the crankcase. This cover also supports the gas tank.

These engines were noted for the crank pin working out and rubbing a hole in the black plastic cover.

The trimmer starts and runs like new, or maybe a little bit better.  (fuel line) 15min work +coffee break included ;D     

@660magnum , the back cover is in the picture.

On the bench I still have the Mac 1000 /Partner p100.Got the suspesion half-fast fixed now the manual oiler is next on the list .

Need to order a starter  pawl and some 80 micron screen .It seems the flocked clip on style filters for these old duffers are rare as hens tooth,thus the screen . Working 7-12s it's next to impossible to find the time to wrench on saws .
