Also check the stop screw for signs of it having moved (it's the one that looks like a threaded shank with no head). If the screw is backed-out too far, the blade sticks.
Otherwise keep your SN95 away from the '68. They obviously like eachother.
i had the same sticky pedal. it was cause that throttle screw started rusting to the peice of metal that it touches. u can either sand it down or put duct tape around the metal piece. i didnt have either one of those so i wrapped a band aiid around it and its smooth now.
i believe your problem will be build up in the throttle body.....i have seen this problem before and as stated earlier some throttle body cleaner should solve the problems....
