I have a 1980 Merc 9.8 with the Tolloston Carb that is giving me fits. It starts up ok....runs for a 10 secs or so and gets choked to death with fuel....as it takes it last breath it comes running out of the carb throat like hell.
What I have done so far:
* Replaced the engine side of the fuel line connector(activator pin got stuck in the corroded ball bearing or whatever in the line connector end and ruined the O-ring). Also replaced the fuel line connector) - No fix
* Took carb apart soaked everything with carb cleaner and cleaned it all. Drove 40 miles each way for an $8 inlet needle valve - No fix
* Interupted kind marine tech at work nearby and had him adjust the float level and set the idle screw to 1 1/4 turns out from seat - No Fix
* He recommended a new float if problem continued so I ordered and replaced the float with a new one - No Fix
That is where I am so far. Now when I said I soaked everything with Carb cleaner that included the old styrofoam-like float, and all of the various pieces/gaskets etc in the layers making up the fuel pump assembly. They appear to be still intact and in shape etc but could that
be the issue with the over loading of fuel?
Local Merc dealer wants $67 for a complete carb kit that includes all kinds of stuff besides just the gaskets and the stuff I have already replaced.
Any suggestions/help will be greatly appreciated thanks.
