how can i get full throttle?

[65notch]

i was tinkering around under my hood today and decided to check if my carb is opening all the way when i put the pedal to the floor...and im not..im getting my primaries and like half of my secondaries.

im not sure how to adjust it now...i know it has to do with the lever attached the the pedal because it can only move so far(hits intake manifold and almost hits firewall.

anybody have suggestions on what they have done to cure a problem like mine?

i have a 289 with edlebrock 600 cfm carb.

Is the carb vacuum or mechanical secondaries?

If its vacuum the secondaries would only open up while the engine is running with a load on it (i.e. going down the highway @ WOT above 2500 rpm or so)

If its mechanical... there could be an adjustment issue

Most carbs have several holes in the throttle plate to mount the throttle linkage either farther or nearer to the pivot point. Mount yours closer to the pivot point and it'll open quicker and all the way.

mechanical secondaries

and the carb has 3 points to mount...its already on the lowest

As long as you are getting the full open on the primaries, it is carb adjustment for the secondaries. Mine are vac. and only get them to open when driving. If yours are manual, then I would look for the adjustment on the linkage as mentioned.
