Hi Campfire friends, I finally took the mighty Zong out for a spin just to see what changed now that I have installed a 90C thermostat. On a day when it was 87F the left radiator started out at 86F. In 5 minutes of getting dressed time that went to 128F, after 15 minutes of stop and go traffic that was up to 202F and after a very short bit of Interstate and back to the garage the temp was 171F. At the oil sight glass the temps were 84, 88, 172, and 197. I conclude that the engine is getting to a higher temp, almost enough to boil off water and most likely well over the temp needed to get rid of fuel. I'd say we have more than enough cooling for really hot days and the hotter thermostat warms up the engine faster. Only an oil analysis can tell if this reduces the % fuel in the oil, I am very hopeful.
