[AT] Need help troubleshooting engine/compressor

[Bo Hinch]

Cecil , those were some very nice little compressors and from my past
experience with them , I would first remove the carburetor , look in the
barrel ( engine side ) right next to the butterfly and you should see at
least three very tiny little holes .Pull a bristle out of a wire brush and
use it to ream / clean out holes and with carburator apart , blow all air
passages from inside out with air pressure or carburetor cleaner .
After reassembling carb. , I would remove air intake cover. I think you
will find it stuck open ( should be closed with little to no air pressure )
and determine why it is stuck open such as a blown o`ring hanging up or
whatever . You also have a regulator valve that operates the air intake .
Just follow the small line going into the air intake manifold . I think it
also has a diaphram in it that does go bad . Also I disagree with quote
from your previous email
 ((( The engine must start under load until the
compressor reaches 40psi, then some regulation begins.)))
Last but not least , NEVER , NEVER put any part of a human body over the
compressor air intake .If I can get some junk moved around , I think I
still have a manual on this unit which would be very helpful to you .
