Hey guys my friend has a 1993 Lx which has been converted over to Carb. We just recently installed a Summit ready to run distributor to get rid of the stock ignition box that is meant to be used for carburetor. Its a new distributor that was never used, we just had it packed away SUM-850303 is the part number. Its not produced anymore. http://www.summitracing.com/parts/sum-850303/overview/
The problem that we are having is that when the distributor is hooked up to a Summit CD Ignition Box the car misfire extremely bad between 2500 and 3700 rpm. The box we are using is and older Summit Ignition Box with out the built in Rev Limiter that the newer style boxes come with. The box has had very limited use. It was packed away for a while as well.
If we disconnect the Box the car runs fine throughout the rpm range. The car did run better with the Ignition Box on it, other than that bad rpm gap that we had.
What would cause this. Would it be the vacuum advance, and if it is why would it do it. I hooked the box up to my 1987 EFI setup and I get full rpm band without any problems so I know the box isnt bad. Any help would be appreciated. Thanks
