Re: carburator cleaning
I would drain each carb by removing the float bowl drain plugs,pump the bulb a few times to flush them out, then replace the plugs, fill your fuel filter with carb cleaner(like B-12 or other) and using your primer bulb, pump the carb cleaner into each carb, leave it a while or overnight, then drain carbs again on to a clean rag so you can see what comes out(the rag is also good because some of the carb cleaners tend to remove paint) Then run engine on your regular gas/oil mixture to get oil back into the engine. I know this works because my motor is a 1999 Yamaha 90C and I've never had the carbs cleaned at the boat dealer and I've never had any carb/gas issues at all since I bought it new in 1999. This draining and flushing of the carbs really only takes a few minutes once you do it a couple of times and then you know your day on the water isn't going to be ruined by some junk in the carbs. Good luck!
