when no pressure on the gas pedal the pump setting should be on the stop. when you push it all the way to the floor the pump should be 100% open. i am thinking that there is a difference in the throttle linkage somewhere that gives the wrong leverage and hence not enough travel. changing the lever arm length somewhere in there should cure that.... if that is the trouble.

so to reiterate, examine your two throttle linkages (if you have both) and check the distance between the pivot point and the ball socket. somewhere i believe you will find a difference. another possibility is that you have an adjustment problem and you are starting with the pedal partly depressed and arent getting a full stroke. this could just be an adjustment solution. solved by shortening the link between the pedal and the first pivot.

also in my 240/300 when they assembled it they put the pivot point in the wrong hole on the firewall. we drove it that way for three years before we figured that out. of course we fixed it right before we sold it.
