You have two problems, neither serious First, the carb's fuel bowl float level is a bit too high. When you stop "aggressively", gas slops out of the bowl vents (the slash-cut tubes on top of the carb) and right down the carb bores, momentarily flooding the engine. There are several fixes of some complexity & cost, but the simplest, if you're happy with the way the engine runs now, is to get a 6" piece of 1/4" ID Tygon clear plastic tubing from Home Depot or Ace Hardware. Fold the tubing in half, and with a very sharp knife, cut HALFWAY thru the tubing, so that when the tubing is not bent, theres an oval hole halfway thru, in the middle. Hook the open ends to the two bowl vent tubes leaving the plastic tubing arching up a ways with the oval hole you cut as your bowl vent..Because its higher up, fuel will still slop out but won't make it to the throttle bores, and will run back inside the bowls instead of flooding you engine. Cost- 30� or so for the Tygon. The arched tubing should fit inside the air cleaner without touching its top (Trim as req'd).
Second problem-the engine not turning over when hot. This is often due to a poor connection of the big grond wire from a bare spot on the frame rail to a bolt on the transaxle. Usually, removing the grond cable & wire brushing under the connection area restores good starting. Occasionally, you need to do both ends of the cable. And if your Pantera has no ground cable, add one today- this is vital for good starting, especially when hot.The real fix for hard starting when hot is a much more powerful gear-drive starter. My 10-1/2:1 compression 351-C will spin fast & start on the 2nd turn when smoking-hot, with a gear drive starter I added in 1989. All the vendors carry them, they are half the wt and install more easily than stock.
