Gene:
we seem to have established you are running rich, VERY rich,In my 806 operator manual (gas)their is suppose to be a adjustment needle in the center of the anti-run on valve.(fuel shut off) you are to lean it for light work. Well many have been replaced and they don't have the adj. screw just a shut off valve,(solonoid) guess too many people run them lean and burned a piston or two??. what I did was to lower my float a little more (1/8") and it helped some, you can put an high speed needle in it from an M-400-450, and lean it like you do on those tractors, Gut feeling is something is a little too rich in the carb.Some carb rebuild shops leave too many things to chance I hate to tell you to lean it up and you are masking the real problem . Try shutting the fuel off at the tank with it running and see if it clears up just as it gets starved for fuel that will just about prove it is rich at the carb. is the timing retarded? that will act rich also. You can turn the dist. while it is running and hear if it is right, than put a timing light on it and see where you are at. Sorry you have an ill iron horse, George.
