I have a 1500 twin cam ford engine that is turbocharged and is sucking through a weber down draft carb. I am having some trouble tuning the engine for good throttle response. when the jets were to lean I had to advance the timing a great deal to get the car to run well, but it would start to det- onate badly. now that I have installed larger jets in both he primary and secondary circuits he car runs much better with lower advance. Is this normal? It seems I can keep jetting the carb bigger and the car keeps going faster. I am almost at the limit of the jet sizes. I also have large air correctors in the primary and secondary, should these be set up for best high RPM operation? any info would help,. thanks chuck gerarden ihnp4!drutx!druhi!vuser
