[QUOTE="Pheasant Surprise, post: 4722954, member: 1103"] Sounds like it’s been seriously fiddled with, and not in a good way. Can you take some photos around your compressor, particularly around the carb linkage and governor/feedback linkages? Possibly quite a different setup to most diesel road tow compressors which, once they’re put on load, will freely adjust their revs based on air pressure feedback, there’s no manual rev control. They simply have a rotary screw type compressor with an unloader valve (throttle body) on the intake side. You can only load or unload them. Yours reads like it has a manual throttle control, which should hold the throttle in the desired position with a spring linkage back to a governor to pull the engine back to idle once full pressure has been reached. Kind of like a petrol reciprocating compressor - it’s either full (set) revs or it’s pulled back to idle. Sounds like it’s missing the linkage then to pull it back to idle at full pressure. [/QUOTE]
