86 ROUGH IDLE

1986 Toyota Pickup • 4 cylinder 4WD Manual • 245,000 miles

I have an 86 Toyota pick-up with a 22r ( carb) engine. The problem I am having is when the engine is cold, it runs very rough and will shoot flames out of the exhaust. When it warms up, it runs like a new truck. Since this began, I have rebuilt the carb, replaced plugs and wires and used that stuff you put in your gas tank to clean the system. I dont know what else to try. Please help me.

Is the ignition timing correct?
Have you checked the valve clearances?
