Gets hot and stalls out
On an overcast, 85* day at cruising speed it will sit at 180*. On a hot day (95+) it will go to 190*. Stop and start (or sitting at a prolonged light) it will go to 210* or a tad higher. What I think a lot of people are missing is that the temp climbed well above 210* after sitting for 5-7 minutes, meaning no airflow during that time. I think - again, my hypothesis- that it started with the fuel that was in the carb, but the fuel in the lines was boiling off and it stalled. Again, I could smell the fuel when I took the air cleaner off but I couldn’t/didn’t see any. That theory lines up with other times where it takes a little longer for the car to start (I.e. will turn over for a few seconds longer than a “normal” start) after sitting for 15-30 minutes: enough time for fuel in the carb and top of the lines to have boiled, but also enough time that fuel below the filter (and possibly the pump) to cool and start the car.
Fair enough. For reference, this is what I’m looking at.
