I have a 2006 25HP Yamaha. The motor acts like it's flooded after I run it at full speed. It starts on the 1st pull every time, but has no power until I pull the choke out 2 -3 times and quickly re-set it after its warmed up, then it runs normally. As soon as I back off the throttle, it does the same thing all over again. Could it be Timing or a carb problem? I have opened it up and everything appears normal. The motor has less than 50 hours of run time. It has new plugs and the Carb bowl has been cleaned.
Thanks for any advice.
