Just looking for opinions, possible solutions. My 40hp Mercury always fires right up and runs great but on occasion will not start after starting up and shutting down repeatedly (maybe off and on 5-8 times and going only 1/4 speed or even less during those times). Sometimes I will have problems starting, but then the motor ends up turning over. Sometimes I may have to let it sit for a bit. I guess my question is - Should I take her in for service and have my carb serviced or continue running her as is? Again, it only happens on occasion, but I would hate to have it not start at all one day. I appreciate your thoughts and opinions on what I can or should do. Thanks.
