  1. You said you see some smoke coasting and then see more smoke when you accelerate after you were coasting? If that’s correct, then it’s valve related. When you’re coasting the engine creates more vacuum, pulling oil by the valves and into the cylinder, then when you accelerate you burn the excess oil and you see it more out your tailpipe. You may also see smoke when you first start it up in the morning. If it’s rings, you will see smoke every time you accelerate from a stop sign or traffic light. 

  2. Any type of wet lube attracts dirt. Like wd-40, chain lube, grease, etc. That’s what carb cleaner is for, to get rid of the garbage that is preventing the linkage from moving freely. If it has a cable going to the carb it could be frayed inside the cable housing and not allowing it to idle back down. I had that happen on a Datsun pickup.

  3. When you tried the wire trick, could you blow through the line. Mine had a lot of gunk in it. I would think I was all the way through and I wasn’t. I couldn’t blow through it. If you could, then either you still have a lot of trash in the tank or the problem is somewhere else. Make the lines are clear from the carb to the tank before going through the trouble of pulling the tank again.

  4. I had this problem on a 1970 Datsun truck, it had been sitting a while. I pulled the tank and used a coat hanger. Kept jamming it through where the fuel line attaches, until it reached the bottom of the tank. No way air would have cleared it. Make sure your lines to the tank are clear.
