Not sure if this is related to my high idle issue, but I noticed my fuel guage only goes up to the 3/4 level despite just filling the tank; the oil Temp level never never increases; and the oil level never rises either. They all engage once the ignition is engaged, however it seems the idle remains at 2200-2500 RPM. One other thing I tried was to screw the idle adjustment all the way in to see what happened- nothing!
Appreciate all the help, I am determined to figure this out without taking it to the mechanic!
