"I have a pair of DAMD 40B'
"I have a pair of DAMD 40B's. One engine will not develope full RPM. It will max out at about 3,100 RPM when it should wind to 3,600. It blows white smoke at around 2,500 RPM and up under load. It vibrates more than the other. I checked intake manifold pressure and one is 16psi and the other is 17psi at full throttle under load. The book indicates 14psi is the minnimum. These are 2300 hour engines. Low RPM seems like fuel delivery but the white smoke is more like not enough air or unburned fuel. What do you recomend for the next diagnosis check?"
