Anyone know what would cause my 1977 Mercruiser 120 to stall after running only 1 minute, or so? Only way to make it run longer is to continually "feather" the throttle.
Last time it stalled, I took a look inside the carb and found very little gas in the bowl (about 1/16th. of an inch) This makes no sense to me because the new fuel pump tests out good for volume and pressure.I have tried the following : new fuel pump, new gas filter, and nearly- new re-built carb. Fairly certain that there is a faulty part in the Rochester 2 bbl carb that is the culprit, but don't know what part would be causing this problem. Don't understand how gas could be getting to the carb, but not filling the bowl??? All filters are clean- even the little one in the carb body. Any ideas out there?
