I have a Road Demon 650 on a 351 with Edelbock Air Gap intake.
Here is the problem, after a sudden stop, as when I was checking out my new brake pads I have an idle surge up maybe 800 RPM and then idle will go back to normal around 5 to 10 seconds later or if I blip the gas pedal.
THIS SEEMS TO HAPPEN CONSISTANTLY BUT ONLY ON"PANIC TYPE STOPS" situations.
I thought maybe float level is screwed up, but wouldn't the car stall intead of surging upward ? Anyone have any advise, only other problem is running a little rich and hard starting, choke works but comes off too fast so you have to feather it awhile till it warms up a bit or it will stall until it is fully warmed up.
