When you take off the front bowl, take a picture of both the surface of the block and the main body. As far as a fuel ring, you need a good plug magnifier to see it, and doesn't show well right away. You can look at the end of the plug for fuel as well, here is a picture from another site to show you.
I may have a few pics of the M-Blocks and the carb body...if so I'll send them to you, If not I'll take a few.
Since I switched to 20/50 synthetic oil I noticed a slight splash of oil around the base ring > this is why I was using a magnifier to look for the fuel ring.
Checked timing > 14 initial and 35* total. I could up the total advance to lets say 38* to see if it pulls any more RPM out of the engine.
