I have an ampac trench roller with a lister petter diesel that starts right up idles fine and even revs on up just fine. It puffs alittle black smoke at start up but it all but clears up after a few seconds. The problem is that when I turn on the vibration it just bogs down. I put new fuel and air filters on it and not much of a difference no fuel leaks the only thing is that I think the Woodward solenoid is bad because it will not turn off by the key switch. If anybody has any thoughts or suggestions it will greatly appreciated.
