Put the boat into the water and tested WOT and response. Lost several 100 RPMs and was sluggish trying to plane. At the dock idle was erratic with sneezing. Thought maybe was from a combination of old gas, dirty carbs, and old plugs. I idled on muffs for few minutes in the back yard and idle got worse with more frequent sneezing.
When I cleaned the upper carb found it to be just fine, so decided (after researching here, thanks) to check the reed blocks. Wow! One reed in each the upper and lower blocks were nearly gone, and 1/2 of the total reeds showed this loss or chipping damage. I was able to rebuild two blocks by salvaging those remaining undamaged reeds, and ordered two used blocks off Ebay. Now, just waiting for the reeds and gaskets to arrive.
What's next? Been wrenching on outboards all Summer.
