Thanks for the responses. Who has TBS needles on-line? Haven't located any. On the vent hose, good thought. It believe it was pinched initially after I had the tank off last week. It died so bad then, I switched to reserve even though I knew there was plenty in the tank. I believe it is most likely a fuel/air mix problem at the particular conditions. It started happening immediately after installing the Feak, jets and shims. Can't be to quick to rule anything out. My wife's car air conditioner quit a day after an oil and filter change and tire rotation. She was sure they did it. I said no way. Wrong! They disturbed a wire harness changing the oil filter. A day later the fan wore through the wire controlling the AC compressor clutch. They figured it out after they replaced the compressor and it still didn't work.
