[AJD] D John Deere carb

[Gary Epps]

I am trying to clean up the carb on the '37 D.  I now have it off the 
tractor and am now puzzled.  Acorrding to the manual SM2000 it should have 
DLTX-16 but it has a DLTX-13.  The bottom of the bowl is enbossed DLT 7.  It 
is not the brass carb.  Is this the way it is supposed to be?  Do all these 
numbers go together?

I left gas in it too long and gas now will apparently not run into the carb, 
ie nothing comes out the bowl drain.  Does the engine need to be turning 
over to create suction to get gas into the bowl?  I plan to soak the carb 
tomorrow in carb cleaner.  Are there any issues I need to be aware of?  The 
manual says to soak it for1 to 2 hrs while the carb solvent I bought today 
says to soak a carb for 20 to 30 minutes.  Have you guys got any advice for 
a rookie?

Thanks, Gary
