Hi I have an older hitachi ex150lc5 that I am having issues setting up the throttle motor correctly, it worked fine after installing new step motor and new throttle cable, but now after working it about 6-8 hours it slowly decreased rpm’s and have tried resetting the throttle probly a dozen times, I could hear the motor trying to move but now it just gives a short power bursts, and can’t get it to calibrate? Any info would be awesome! anyone with similar I would be grateful for any information! Thanks!
