need help adjusting Holly carb
I have a 302 with a holley single pump 4bbl on it. I need some help adjusting it. I recognize most of the main parts of it, including the two adjusting screws on the metering plate. The best I can do is get it running smooth. I've been fooling with it and it seems to run ok, but I've lost the compression braking that i used to have. And it back fires through the carb if you let the rpm's drop and then get on it real quick. Is there any printed info out there, or some sort of measurement i can make?? Please help. Thanks ahead of time.
