I'm a new member here . Started working on getting my 2.5 hp tohatsu running cleaned the carb checked fuel lines checked to see I'm my spark plug was getting spark. Got it to run but found oil on the threads of my spark plug and couldn't get water to come out with the foot in a bucket of water. Is the oil on the threads very bad and does the water not squirting out mean my water pump is bad? Any help would be appreciated.
