After a year of great service my 850 Street HP has a new problem. Carb intermittently decides to flood at cruise. AFR at 14 at idle. 14.8 low speed cruise, BUT randomly will flood (drop to 10 and stay there) at light tip in or more commonly at 60 mph cruise. Have disassembled carb twice, replaced needle valve, slightly increased high speed bleeds, replaced float with a nitrophyl, reset float level multiple times and checked fuel pressure at about 6.5. BTW, yesterday i drove the car 75 miles at 65 mph at 14.5 with no problems. This morning 20 miles zero issue. This afternoon it started again.
