Ok,I can understand what you'r telling me,but I personally think it should n't be that way.thank you very much for your time.so it's normal for my 58 to act in this manner.when I say whip the throttle I mean I set the throttle back all the way down then in less than a second quickly give it full throttle.and that's where I have this problem wich I find kinda strange.but if you say this is normal well I guess I'll have to live with it thank's agian.
