FINALLY got my shifter problem fixed, so on to the new one. First off I don't know the history of this truck, so it could be anything. I have a mikuni carb with a new fuel filter and pcv valve. Went for my first real drive, went to get gas (first full tank I've put in this truck) and dumped in a can of seafoam. Driving down the road at a steady speed could be 35 or 65 and the truck will hesitate and it stalled a couple of times at a light. It doesn't seem to like to restart well when warm (3 cranks) but starts fine when cold. The stutter seems to get worse the warmer it gets. Kind of intermittent, pretty sure it's fuel related as sometimes it runs just fine.

I don't have a fuel pressure gauge. Can I just crank it and measure how much fuel I'm pumping?

Ideas on the best place to start?
fuel pump
carb
vapor lock
gas tank debris
