Well if you fly at the Seahawks field atleast you have got plenty of room for a dead stick! How did you even get that thing to balance? I've got an ST 2500 in mine with a killer battery towards the back and still added tail weight! My G62 on my Giant Stinger uses a Velocity Stack and the carb is exposed out side the cowl and have no problems. Get the carb number and go to a shop for a rebuild kit. You may have a bad diaphram.
