When the temp getas cooler the carbs will get leaner not richer. Probably should have tuned with the air filters that you will run because they alone can change the tune. We see about a 30 to 40 HP drop with the filters installed on the Webber carbs, they richen them up by restricting the air. Everybody I know has to tune on them pretty regularly and I let them know this up front. I do not want them mad at me when they have to play with them when the weather changes a little. When right they do run well and the camshaft is pretty important for sure. Good luck, Keith
