Mitsubishi FGC25K 0R FG25K:
Idle issue. Mitsubishi FG25K AF17C090031

Hello, I have a Mitsubishi with the electronic governor and Cobra Impco regulator. The Vacuum switch is unplugged currently. I don't know how the vacuum lines are supposed to be attached. The issue is when you start the lift it idles at about 1800 rpm. As soon as it is put in gear, it down where it should be as long as it is turned on. As soon as you turn the lift off, it idles high and does the process over. The controller in the back of the lift along the counterweight has a vacuum line which doesn't push or pull vacuum. As soon as I apply the vacuum line to the vacuum switch the lift completes bogs down. Any help on vacuum would be appreciated.

Are you still working on yours? Customer won't let me have it until next week to work on it again. Key on the throttle motor responds with the pedal. I don't want to overthink it but the setup stinks, model j with an electronic governor. I'm hoping to have some luck with it then. Any other pointers would be helpful.

Got an FG25K doing something similar, but no response from accel pot. Found lock off stuck partially open and would not click or open with power. Now, the machine revs like **** and wont idle down. think the ECU is shot!
Too expensive, saw kits online to old carb style, $600
ECU is $1800!
FYI, the vacuum lines I have are: from ECU to base of carb. Dist vac line (small) goes beside ECU port at base of carb,
Then, vent at lock off valve has 3 ports. rt port to hose at right of converter, teed into air snorkel, Left hose goes to base of converter, and last left hose goes carb
