I am restoring a 1986 Stratos with a Mercury 150 XR2. Motor hasn't been in the water in several years but I have cranked it. Did a cold compression check and got 103 to 106 in all cylinders. I know the carbs need at least cleaning. My question is, since it has sat for so long, should I do a complete carb rebuild or would a good cleaning suffice. Owner said it ran fine till he parked it. He's a good guy. I have redone water pump, lube, plugs, fuel filter. Any other suggestions?
