Black Fuel in Carb....
After replacing the carb with a rebuilt one, the engine quit with greater frquency until no restart was possible.
I drained the carb and the fuel that came out is black. Please someone set me straight here and tell me it's likely a valve issue? Fuel going in is clean as clean as can be (2 filters, electric pump, water seperator, 0 ethanol..) Plugs are sooty. Cold compression test says #1-3=110psi,#4=90psi my guess is #4 is the culprit..? I shot a few ounces of MMO into the plug holes and it started to leak from the carb flange...(carb is removed) Any insights? I did have a leaking water pump that got some water into the oil last fall. I replaced the pump and did 3 oil changes, engine ran fine up until this black fuel happened... I will clean the carb and see if she runs again before taking it appart as I might be faced with having to remove the A4 altogether to get at the valves... Engine acess is horible on the Grampian Classic 31... |
