Hi All, I just bought a 74' CL360. I was told it sat for a while before the previous owner tried to get it running. There's hesitation about 2000 - 3000 RPM, then it's off & running. It idles fine. I can avoid it by revving above that before letting out the clutch, but that's just annoying. I've cleaned the tank, petcock & replaced the fuel lines. Just had a shop clean the carbs, set the timing, check the valves etc., they couldn't get past the issue either. It has good compression on both cylinders. Got to be something simple right?
