[GreenKeys] UGC-74A cleanup

[Bill]

Hi Jim,
Well on the 28 and KSR base I just finished, I used Gumout carb cleaner 
in the spray can. It dissolves and washes away all the dried grease and 
crud. I used a small brush where needed and then compressed air to dry 
it. Worked good for me.  Also used a sonic cleaner for some of the small 
parts and bearings that had dried grease in them.  I put Lysol 3-in-1 
cleaner in the sonic unit and that did a good job. Rinsed in water dried 
with air then repacked the bearings.
