[AT] stuck good on a WD 45 engine question!

[jvhollon]

John a lot of ideas some good some not. First thing I would check is the oil 
cup on the air filter, make sure it is not filed with water over filling 
it.Then look at valve guides.Compression test told you no cracks that would 
let that much oil in and if ring ends were lined up one would think 
compression would drop if it was letting that much oil in.But what do I know
