I posted on another thread: engine has sat for 8 years unused. Got a leak down test with bad results and a was told it was shot. After some reading, think it's salvageable. Plan right now is to replace head gaskets, replace fuel lines, and clean out carbs and then run with cleaner and see where I'm at. So today I pulled off that cover to look at the carbs.No dust out on the water.----What is your motor doing / not doing that leads you to the questions here
