Today was my first day taking out my 1978 PRS Club Ford 1600. As I was going through a chicane the throttle stuck wide open and revved to the moon. At least 7000+ RPM for a few seconds before I realized what was going on and was able to turn it off and safely pull over. In the pits I found a broken zip tie had gotten stuck under the pedal stop and was holding the throttle cable tight, I went back out and the car ran poorly. It would rev cleanly for a few thousand rpms between 4-5000 but not always. It was not consistent as to which gear or throttle position it would rev cleanly. It felt like the equivalent of the car on the rev limiter or a bad set of plugs. I would never run cleanly below 4000 rpm or above 5000 rpm
Any suggestion on where to start? I was thinking plugs but I am not sure how an over rev would have fouled the plugs
A friend suggested I may have skipped a tooth on the timing. Is there a manual out there that shows how to reset the timing set?
Also, how much advance do we run with these cars and what rpm do you all shift gears?
Thanks
Marty
