87 TRX350 floods on hot restart.. GAHHH!

Greetings! I’ve spent a ton of time and a little bit of money trying to get this old bulldozer going, and for the most part it is working well… unless we shut it off and let it sit for 15-30 minutes, then it floods on restart.

The details:

– New fuel pump (the proper regulated one)
– New Caltric carb, stock jetting, pilot/fuel screw 4 turns out (this is where it idled the highest when warmed up, between the two points where it started to drop idle)
– New fuel filter
– New air filter (UNI)
– New coil and wire
– New battery
– Oil temp switch bypassed, manual fan switch installed

– Starts well when cold, choke on. Have to take it off choke within a few seconds and then manually hold throttle until it gets a little heat in it to idle
– Idles fine and runs well
– Will continue idling and running well until we shut it off.. have ridden it over an hour nonstop and it is good
– Can sit for 0-15 minutes or so and it will restart (no choke or throttle)
– Sitting longer results in a no-start. Have to wait for it to cool down for quite a while before it will think about going again, not sure how long because I usually leave it in frustration and play with it the next day.

The obvious answer: don’t shut it off LOL… but I really would like to get this thing starting reliably if it is possible. It was such a heap when I came into it, and now after all the time and effort, it is just teasing us! Haha…

From my (LIMITED) understanding of carbs, the pilot/fuel screw between the throttle slide and the engine is what has the most influence on starting so that is where I should be messing with it… or am I missing something?
