alrighty fellas sorry it took me so long to respond back. built me a leak down tester and followed steps coverd in other posts. it passsed, but i did notice that my my right cylinder appears to be leaking some coolant. i would have thought that would have showed up on the leak down test. im running 34mm carbs with 45-50 pilot, the air screw was at 1 1/2 turns i was thinking that maybe tighten the air screws all the way and go from there. but i should prob. take off the right cylinder and fix that leak first?
