My 10 hp johnson seahorse runs for a minute and then sputters and dies....QD 23A 1960???? I ran it for about 20 minutes one night and then the next night it started and ran for about 10 minutes.....It seems to get fuel to the carb for a minute but it does not maintain suction????? if I squirt a little gas in the carb it runs for a second....I have removed all the hoses and it seems like there is fuel in all them so no blockages as far as i can tell........there is a spot where 2 feul lines meet one is labeled in and the other out is this the fuel pump???? Is there a diaghram in there that could ahve gone bad???? what do you think.....any help would be appreciated...
