I an not sure but have been wondering about that. This engine has less than a thousand miles on it so to be that down on power there has to be something going on. I just put the lightest advance springs in the distributor so I will have 35 degrees total all in by 2000 rpm next thing of concern will be the carb. what is best way to check opening of secondaries? I have used a twist tie on rod before to check for movement.
