As an afterthought -- I should add that the idle adjust knob has no effect since the valve adjust, so something was indeed reinstalled a little bit "off" from original. It also seems that my accelerator cable or throttle may be sticking open a bit, as the car seems to want to drive itself at times (i.e. doesn't always like to decelerate when I take my foot off the accelerator pedal).

Guess it's time to lube the cable and fiddle with idle adjust???

Thanks again,

Chris
