I have a 1985 Cobra with a Detroit Deisel and Allison Transmission. One of the previos owners had installed a Propane injection system on it but I have no specs on how many column inches of water the regulator should be set at. Also the engine puts out lots of black smoke going up inclines and the speed drops to 25 to 35 MPH.
Any suggestions?
