[AT] Anyone heard from Bo Hinch?

[charlie hill]

Cecil,

I'm sure Bo can help you with this better than I can.
After being around a lot of Detroits I can tell you that
the idle is controlled by "the rack" and that isn't something
you need to mess with without experience because if it
isn't right the engine will run away until it hand grenades.

The problem you are having is most likely related to the pressure relief
valve.  The Ingersol compressors I'm familiar with don't have detroits but
I think the set up is about the same.  There is a valve on top of the 
accumulator
tank that is piped to a solenoid wired to the start button.  There is a rod 
that runs
from the air end of the compressor to the pump on a JD or Cummins.  I'm not 
sure
how it's set up for a detroit but that calls on the governor based on air 
demand.
If it's not right it will shut the engine down or rather lug it down until 
it shuts off.

Of all the screw compressors I've dealt with over the years, if they are 
giving problems
it is somewhere in that system.  I'm sorry I don't know the correct 
terminology.
I never work on them because 1)  they weren't my machines and 2) given the 
nature
of compressed air I didn't want to risk tinkering with it.  I leave that to 
folks that know what
they are doing. I've never seen a compressor come unglued but I have seen a 
Detroit run away
and grenade.  It ain't pretty! It will make you want to run!

Bo:

Thanks..  I had a ransom virus in my computer and I had to start over
lost everything from 2007..  My old Ingersoll 250 rotary ...........   I
had to start it up in 12 deg weather a few weeks back.  3cyl
detroit...   It finally fired up with some ether like a typical
Detroit.   However, when pressure would build up and it would try to
idle back, it would just die.  I don't have a tach on this machine..   I
was only needing it at the time to air up a tire.   My electric
compressor was in another building., and my small compressor used a
Honda that would not pull start with the cold..   I finally connected a
1/2" hose barb orifice to the other valve on the compressor and bled
enough air to keep the engine throttled up and hold at about 100 lbs
pressure.  I got the tire aired up and then discovered the oil filter on
the Detroit started leaking.  New filter and new 15W40 oil, but it was
cold..     I really don't find a place to set the Idle speed on the
Detroit.. I know this is a rather dumb question.
