55 mercury mark 6 timing

[jab2373]

I posted a question yesterday about this silent 6 starting and stalling problems, and was told to check compression and spark, also checked fuel, but it seems like it is getting to much fuel almost like the timing is off, Is there such a adjustment for this model, and how do I get the magneto off to check it.

Hi Jab<br />If your compression is good and the spark is good then you have a fuel problem. If you are getting too much fuel. Remove and clean the carb. Your float or float valve is malfunctioning in some way. Maybe do to crud or what ever. You also may need to adjust your high-speed needle and from your previous post sounds like the low-speed circut is pluged, or the low-speed needle is maladjusted. If you have not serviced the fuel system lately I think it's time now. Also if you keep all posts reguarding your little merc under one topic you will get better more efficient help. To get to the magnito you will have to remove the fly wheel. Sure wouldn't hurt you have a look under there too. Might as well have a look at you lower unit and water pump empeller.
