"I built a 350 chev engine from a seized CC 283. Then I built a skiboat, from scratch, to put it into. I used most of the 283 parts, including the intake manifold and carburetor (Rochester 4 jet, not quadrajet). I repaced the old ignition with a GM HEI ignition. The engine runs very cold with no thermostat. I have a terrible flat spot when I accelrate hard, from an idle. The accelerator pump, appears to be giving an ample shot of gas. So, what's the problem? Temperature? ...or maybe Jetting? Any thoughts would be greatly appreciated."
