I have a 1988 20hp Johnson. Starts good, low idle good, wide open runs good. Anywhere in between it has a miss. If I run it a long time at wide open it seems to stop the missing for a while but will start back up. I rebuilt the carb over the winter. It was clean, the bowl gasket was broke...
I am trying to get an 1980/81 mercury 7.5 going. I have good compression and spark. I cleanded out the carb and put new diaphrams and gaskets in it. I can pump fuel into the carb with the bulb. The vaccum for the fuel pump seems to be working. It does not look like it is drawing the fuel up...
I have a 1985 Mercury 60 hp 3 cylinders. It has 55 hrs on a rebuild and new switch box and 5 hrs on a new stator and plugs. It starts and idles fine but stalls out when I start putting the fuel to it at about 2500 rpms under load. With no load it will rev up but slower than normal...
