Okay, I have a 73 L16 with a Weber carb. I just replaced the electric choke and topped off the oil. But for what ever reason, it likes to idle at around 1800 when its cold, and 2700 when its hot. Carb is about 6 months old, fuel pump has been replaced with a Mr Gasket universal. Looked at my choke and its set right, and the high idle cam is moving on and off the screw. What do???
