So a week ago or so I go out to my boat and it just won't start. Thinking I got water in the fuel or dirty fuel. Finally get it to start using carb spray but then it won't idle. Have a mechanic look at it and he tells me he backed out both the screws on the carb and either it will clear or I need a rebuild. Questions:
1. Since the carb screws are backed out what will happen if it clears?
2. What do the two screws do? Air and fuel I am assuming.
3. What do you think I can do if this happens to me on the lake?
