i started driving a truck that hadn't been driven in a while. it mostly ran fine, had a demon carb too. but sometime it wouldn't start when cold. not sure what the problem was. i think it was flooding.

another thing it would do, if i would really get on it and get the secondaries open, it would die (while driving) and wouldn't start unless i shot some starter fluid down the carb. i changed the fuel pump and that fixed that.
