Just fitted a new set of 276's to my Rapide. They're properly balanced but the pilot mixture may not be 100% correct yet. Only done a few miles but when pulling up a hill at 30mph in 3rd it occasionally missed a beat. Nothing dramatic, just slightly annoying. It ticks over slowly and reliably but I'm thinking the pilot mixture maybe a bit rich. I know I can play with it but has anyone got any thoughts?
