I just tested it with the factory settings except I changed the high end to: 2-3/4 turns out. I idled a tank (I also lifted the car up and let the wheels spin freely with engine powering). It was better but started smoking around 1/3 of the way through the tank so I pinched the fuel line. The tempature of the air was 77F and the humidity was 55% (It feels like more). Do you know what the problem could be?

I have been getting 20-25minute runtimes with it tuned right and no smoking. Is this normal. Also, I got this car in July and am still on the first glow plug. I didn't think they would last this long.
