Question More on throttle adjustment...

Now here's another question for y'all...

While I was fixing my self-inflicted vacuum leak, I decided to re-check the throttle adjustment. The throttle still won't go 100% open. There is about 3/8" of travel left before it hits the stop. I tried adjusting the cable under the car, the rod to the gas pedal, and even the small arm between the TB and the bell-crank bolted to the motor. No matter how I fiddle I can not get any improvement. Any further shortening of the linkage, anywhere, only raises the idle because things get too tight.

Anybody have any experience with getting that last bit of throttle opening?

Rob,

You donít want the throttle to hit the stop at the engine. Full throttle is adjusted with the stop on the floorboard. The last few % of throttle opening is insignificant for the performance of the engine. Bad things happen if you use the engine stops.

If you think there is way too little throttle, check the accelerator cushion. The internal rubber cushion can fail yet the housing will let you get part throttle. Check this link.

Best,
Grady
