my old 1965 6hp johnson has got some problems lately .<br />at first it ran great , but when the engine was hot it would not restart , i had to wait for about 5 minutes and then it started .<br />but today i went out and it started , but bogged down immediately , and would not restart for a while , and when it finaly did it bogged down again and again .<br />when it bogs down fuel is comming out of the carb , and it looks like the engine is flooding .<br />i checked the spark plugs the upper was black .<br />and i have another question what is suppose to go through the hose that is placed vertical on the side of the powerhead , i see fuel going through is that good ??
