I do have a edelbrock book. I read the whole book and experimented alot. I got the carborator tune to where it should be right now. The timing is right. I re-routed the gas line to where it won't be in the heat and those three things made it better, but I thought hotter plugs would make a little difference. When the engine is cold it has a snap, however when it warms up it is sluggish (like it is too rich). What are your thoughts?
