Help, Cub Exhaust Smoke, Unusual

Posted by Bill 48 NY on March 12, 2005 at 15:24:54 from (64.136.49.225):

Bought a 48 Cub w/Blue (Oil)exhaust smoke and black soot on muffler cap.
Engine runs out good and has plenty of power.

Performed compression test.
Results: Dry Wet
cyl. 1 110 115
2 110 114
3 106 111
4 116 123

Cleaned Air cleaner and crankcase vent tube.
Removed valve cover, it all looked clean.
Changed oil and filter twice in 4 hrs run time.
Added Mystery oil to oil and gas each time.

Now some times it runs with very very little if any blue exhaust smoke and then it goes back to smoking at others.

Any ideas this is driving me crazy???!!!!!

Thanks,
Bill
