I am hearing a pop sporadically while driving at a constant RPM. Whenever it pops you can feel the engine miss as well. The engine is a very fresh 2056 with dual Dellorto 40’s, mild carb web cam, and a stock 050 distributer. Also it runs strong from idle to about mid throttle but after mid throttle it has no power and goes from a smooth sound to a very low throaty sound. It seems like it is rich due to the lack of power after half throttle but it the pop seems like a lean miss. Any suggestions? Maybe multiple problems?
