OK here is an update,


I changed the clunk line to silicone (shortened up a bit) added a heavier clunk, moved the fuel filter closer to the carb to lessen the chance of bubbles, adjusted to factory settings. Started the engine and unless i increase the throttle wile dipping the plane into a simulated dive, it stutters and dies. If i increase the throttle giving it a bit more pressure on the exhaust port it does better. All in all not very impressed at this point.
