having trouble with the motor staying running, i have plenty of gas going to the carbs,the motor will start right up but will not stay running long . when it idles down it will cut off,,,can any help????
Look on the stbd cylinder head near the spark plugs for a black plastic air valve with a hose running forward to the carbs and an open hose barb that looks like it's missing the hose. It's not missing a hose, it's an air inlet but on some motors it lets in too much air and leans out the intake mixture. Cap it off and your idle should return to normal.
