I will look into that. When I plugged the controller in yesterday, the engine was at operating temp. I went on a slight hill behind the house. It would spin up the hill BEFORE plugging the controller back up. But would NOT spin and felt sluggish up same hill. UNPLUGGED it again and it spun up the hill like before. Today, it spun up the hill.
I am not sure what all the the controller does. It has way too many wires on it just to control one thing in my opinion. But it seems to run ok to me.
I still haven't got the high idle thing fixed(either way). Thought I would ask about the controller FIRST. Might work on that again tomorrow.
