Please check my thoughts and add to them...refers to a 70 460 Ford engine. Timing advanced to far, carb was set up to run right. Timing is retarded to get the pinging out. Pinging gone, timing is now set to factory spec of 10 BTC. Now it bogs down on acceleration. I'm thinking I need to go one(two?) step leaner on the metering rods in the Edelbrock 1406 to fix the bogging down. That sound right? Any other pointers/suggestions?
