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

[John Wilkens]

Good idea Jack!  The tractor belongs to my neighbor so I'm not sure 
if we had the air cleaner attached or not.  That could sure cause 
some oil to be sucked up into the cylinders.  I'll check that 
out!   Not sure why it would affect only cylinders 3 and 4 though.   John
