hey guys, i have a 600cfm carb on my 355 motor. cars running rich alot of smoke. ive tried adjusting the idle/air screws did everything. next up is changing out the rod and jets. right now stock jets in the carb are primary main jets .098 and secondary main jets are .095. what size jets should i go with to lean this out. once this is fixed the project is finished and ready to be registered. thanks
