I have a 62 3000 Mk II (tri-carb). A guy at a meet said he used the Prestone flush kit with good results - engine running about 20 F cooler. A Triumph friend said he's been afraid to try it. Any insight on this (procedure, etc) would be helpful. Thermostat opens at 160, car rapidly gets to 190 while moving and gets to 210-220 at stop lights and in stop and go traffic. I just think it ought to run cooler. I have just had the radiator re-cored and fin count increased by 50%.
#2. After the car sat for a while the carb floats (brass) developed microcracks and filled with gas. I replaced them. Everything was fine for a little while and then the new brass float in carb 1 developed the same kind of microcrack and it sank. Could excess fuel pressure cause the float to rise and fall fast enough to stress the float and crack it? I know it sounds like a weird question; maybe I just got a bad float.
