I put a another gasket between the carb block and engine due to a small gas leak seeping through (very, very small). With Scott's suggestion I used a asbetos-free fiber material with a thickness of 0.040 inch. I ran the engine on the ground with a apc 17 x 6 prop. I had to readjust the l/h needles and got it to around 2100 rpm and high at 8100 rpm. I continue to punch it and l to h was smooth. I had to tweek the low end 1/8 rich and now when you go in mid range, it will sputter for a second then even out.
