Today I borrowed a friends Nova carb and the bottom end got much better but still get soft at the end of the tank on the track. I KNOW the engine is tuned correctly. I even had Ed Bridges from EB Mods tune the motor and it still eventually got soft on the bottom. I've checked tank pressure and replaced all the lines. What's the deal? This is a pretty discouraging first time experience with GO Engines.
