My throttle keeps going from high to idle so I turn the throttle to low and then to high a couple of times and it'll stay up for a while then back to idle what would cause this?
do you have auto idle turned off or on?
Off
Welcome to HEF morex ! Push and hold the set switch and key on or start. After bulb check release the switch. Press the display select switch until you have a zero on the left side of the display. What digit is on the right side of the display? Then press the display select until the number 8 is on the left side. What are the readings on the right side at low idle and fast idle. Run the machine while having that reading up and see if it changes when it drops to idle. Report the results. Do the same as above when the display has a number 7 on the left.
