I want to adjust how far my throttle plates open with the pedal depressed all the way to the floor. (I'm making sure the throttle plates are perfectly open.) I've noticed there is a stop under the gas pedal. It's all the way screwed in. So to make the throttle open even further, do I just adjust one of the threaded adjusters in the linkage? Is there any negative to this? I assume that afterwards there will still be enough play for the lingage to return all the way back to the idle stop...
