Mechanical Fuel pump
Last week I had the Webers off doing some maintenence, I cleaned them out thouroughly and replaced all the gaskets. I have also been fighting what I believe to be an electrical gremlin in the ignition. After reinstalling the carbs and running breifly I unscrewed the inlet filter cover on the 2 LH carbs and observed there were small pieces of what appears to be "Black Rubbber" that were stopped by the filter in the Carburetor top. I began thinking that maybe the current gasoline has attacked the diaphram in the mechanical Carter Fuel pump (12 years+ ) or one of the hoses in the fuel line from the tank. 3+ years service life. I have another pump so looks like I have a project for tomorrow. I'm going to have to mix some parts as the spare pump came from Robert Yates Racing several years ago and has a rated pressure that would be very unfriendly to the Webers, even with a regulator. My money is on the pump. I hope it can be accessed and removed with the engine in place???
