I see part of your problem-the kickdown lever that you have on the trans is for the 1 pc rod system. That is longer than the one you need. So in reality the ratio is off by quite a bit. The short levers are for the 3 pc bellcrank system and the long levers, like yours is for the 1 pc rod system. You have to have a short lever! And put the rear hook on your pretty purple return spring in the U on the end of your throttle cable.
