Robb.
Were your top vents open when you cooked? if not that might be your problem. As for actual smoke time, it is going to pick up a taste from your chunks/charcoal the entire time that it is on your bullet. If it tasted too smoky and your top vents were open when you cooked, you might try adding less chunks.
Robb,
What kind of wood did you use? Was it seasoned properly? Those two things can answer your question. Mike's advice are also other possible clues.<BLOCKQUOTE class="ip-ubbcode-quote"><font size="-1">quote:</font><HR>Were your top vents open when you cooked? <HR></BLOCKQUOTE> Give us a bit more information and we'll see if we can help your next cook turn out better.
