I have tightened my cluth about as far as I dare without sacrificing performance and I am still getting beat out of the hole. The engine runs all day at 246-248 degrees F. I noticed if the engine idles for more than 10 seconds that it would not respond when I gave it full throttle. What I mean by this is that when I pull the trigger the engine continues to idle for another 3-5 seconds before it responds once it responds and clears out it continues to run just fine, it is just a step slow coming out of the corner. I don't know if it is lean or rich on the bottom or do I need to go back to the Nova to get the bottom end that I need. Thanks for the input.
