go a step colder in plugs, but you have..you've tried retarding your dizzy and that doesn't work..cheap on money so no tune wtf ecu are u using then..last time i checked..if u built a motor and couldn't get it tuned..why bother driving it..or in fact..even getting on it..if it starts at 4k stay under 4k..
