I recently had a guy rebuilld my 150 merc. and it has hesitation problems and was out of time also. i have started checking over everything and the bleed hose routing is all wrong. i also found that he tried to repair reed block gasket with gasket maker and it actualy plugged up one of the bleed hose ports. Ive got new gaskets on the way. they will be here tomorrow. Anyways my question is if these hoses are all routed wrong is it gonna make the engine run bad and have a hesitaion and miss. I do have have 125 psi on all 6 cyl. carbs are clean also and fuel pump has been rebuilt.
