HI I have a 1989 toyota hilux, I'm having problems starting it in the morning. And a lot of black smoke blows out the back once warm its okay. Though engine still little shuttery at times. I've been told it's a carb problem, though I rang around and no one seems to be rebuilding carbs anylonger

See my answer here.
