Is it just my carb? (not happy while cold)

I'm almost certain its not my timing chain, it was very tight when I checked a month or so ago.

I'll look into the choke unloader, I'm busy rereading about carbs... then I'll look into my particular carb's unloader.

I was playing with laser temp gauges at frys yesterday, I'd almost like an excuse to get one :)

Thanks for the suggestions.

She does seem to misfire if I drive when cold. waiting for it to warm up and having to open the hood when I start it in the morning to stop the bad idling is a pain and I've gotta figure something to fix it with as little money and downtime as possible.
