So my car is running ridiculously rich at the moment. Black smoke, gas smell, fouled plugs, bad MPG etc. I'll toss a pic of the plugs at the end so you can see what I'm dealing with here.
So far I've put new plugs in and after 20 minutes of driving they are even blacker than the old ones. I've also adjusted the carb I think? I turned the adjusters all the way in which should be lean and then backed them out 1.5 turns and it's still rich. That leads me to my question.
Is it possible some trash from the gas tank got sucked into the lines and clogged the return line which forces all the gas into the Carbs because it can't get back into the tank? I'm gonna try and blow through the lines this weekend and take the carbs off and see if I can find anything else, but just in-case is there something I might be forgetting that I should try first?
