I can't get the engine to start with the Holley at all. I was questioning the size of the carb just to get it to run. Wonder if there is too much gas input in the manifold to start with! Doesn't sound as if that is the problem. I am also discovering a 1.5 to 2.0 volt drop at the starter relay in start mode. I am going to increase the wire size to the relay and check the voltage in start mode again. I feel it is either the voltage drop or the size of the carb causing my problem. Any recommendations?
