The Ford Barn

I went out this morning in my Model A and drove about 12 miles to a destination. The temp in the morning was 75 degrees. I drove back home in the afternoon (temp @ 92 degrees) and about halfway home was experiencing carb sputter / cough at speed. I could feel the engine heat through the floorboards, so am guessing high temp was a factor. Tried turning the carb mixture / choke rod a bit but got no real improvement while running. I am using a Tillotson carb that tends to be on the rich side. Car never threatened to stall and idled fine - sputter was worse under acceleration. Engine temp was approx 180 when I got it to the garage. I haven't looked closely at the Tillotson internals, but do not see an adjustment for lean / rich fix. Any advice? Thanks, BW
