It's always best to pull them off to clean them, but at the minumum remove the brass drains from the carbs and spary carb clenaer through the jet inside. If you see any green or black build-up on the brass drain screws, then you really should pull the carbs apart and thoroughly clean them. BS is ALOT better on the MERC's than I, but I tend to get by with all engines
. A timing light and a few other tools is all that is really needed to do MOST repairs on that engine. Them old 2 strokes may drink gas, but at least you don't need a $3500 laptop with all of the software to work on em.
