it has hei and im running 45TS plugs. if the engine is warm and i shut it off and try to start it after about 20 minutes or so the engine will crank over many times before it finally takes off, but if i give it any gas when its cranking its starts but it runs really rough and smokes black out the tail pipe i know it runs pretty rich because i can smell it out the exhaust. do you think i should change jets and rods. if so what size should i go with. it has the ones it came with in it now.
