Rick 01-04-2008 12:49:54 66.17.34.96 28530 Report to Moderator	I have a 1961 chevy pick up with a 235 six cylinder that is not running well. The engine will idle for days but when I get going in third gear it acts like it is running out of gas and spits back and shuts off. I have cleaned the tank, changed the coil, changed to an electric fuel pump, changed plugs wires, points, condenser, and the engine still dies when there is a load put on it. My next step is to change to an HEI distributor but if anybody has had this problem and can give me some answers I would really appriciate it. Thanks [Reply]  [Send Email]

Those old Rochester carbs had some places inside that could plug or varnish up giving problems. Also, be sure you don't have a gasket pluging the hole in the bottom or the baase of the carb that controls the power valve piston. Manifold vaccum controls it, and if it doesn't get the proper vacuum, it can leave the power valve closed, meaning fuel starvation.   [Reply]  [Send Email]

It sounds like you could have a bad fuel filter. I would check that next. Keep us posted on your progress. Bill   [Reply]  [Send Email]
