I have a reman 3.0 I just put in had the carb rebuilt. I took it out on the lake and all was fine for the first 10 mins of running around the lake then It seemed I got a slight pause in the engine and then I started to hear a pooping noise coming from the carb I have a distributerless system...
I bought a new 3.0 mercruiser inboard for my boat I placed it into my boat this week and all I have left is the spark plugs come to find out my spark plugs do not fit.. the threaded area is a larger hole than the spark plug any one heard of such a thing all the part numbers I have looked up...
