Default 6-71 detroit diesel powered Ingersoll Rand air track drill

Greetings from Alaska. My name is Jim and I have been given the task of making operational an
Ingersoll-Rand Air Track Rotary drill, powered by a 6-71v Detroit Diesel.
The first order of business is getting it running properly. When I'm starting it up,
one of the exhaust manifolds loads up with fuel. Mind you that after I put out the fire and actually get it running, it settles down and starts running properly. It's the fire thing that I don't like.
Any thoughts?
Thanks Jim

Exclamation Re: 6-71 detroit diesel powered Ingersoll Rand air track drill

have you run the engine under heavy load a while? The engine may be 'wet stacking', incompletely burning fuel due to low combustion heat/cold engine situation. Check the thermostats to see that they are working. A cold engine will not run well. Check compression. Poor adjustments, Low compression due to bad injecter valves, poor ring seal, and or a worn out engine , will also cause fuel to be dumped out the exhaust.

Thanks for the reply and I'll begin troubleshooting the items you mentioned. This project marks my first old diesel. Could tell me what range the compression should fall in?
Thanks again
Jim

Jim, I see you are in Seward and that brings back poignant memories. In December of 1986, we lost a 9299 American, 165 ton capacity crawler crane over the handrail in 400 ft. of water less than half a mile from Seward. It is still there if you want it. It would be very expensive to salvage The operator jumped off which was good for at least two reasons. First he did not get hurt and second he was still alive to get fired! Good luck with your 6V-71, good engine for a 600-750 cfm compressor.
