Constant Carb Fuel Spills ?

If carb has been working spotless donít finger the float, was nicely adjusted at the carb factory. Itís all about the needle and seat not doing their homework right. Needle tip must be sharp pointy, not rounded, degraded and needle seat not pitted, corroded in order for this cleaning procedure to work spot on. Procedure :

-With removed float and needle, turn carb upside down on a towel placed on a flat clean surface.

-Get a medium wooden stick and roll a thin piece of cotton on tip similar to a cotton swab.

-Dampen in water, roll again cotton on tip to have it sitting firm and doesn't fall off from stick when cleaning.

-Apply an overdose of toothpaste of your brand preference on tip.

-Insert tip on seat, with hand palms holding stick in middle, spin tip firmly down on seat as when polishing head valves on a motor block.

-Remove stick, cotton swab will come out dirty, due to fuel debris building on seat over time.

-Dispose old cotton and roll a new one with fresh toothpaste adhered to it.

-Repeat the whole process till cotton comes out immaculate clean.

-Install needle and float.

-Proper time to change the middle carb gasket for a new one if found severely dried, cracked, faulty gasket will also spill fuel from middle carb as well...

-Close carb, install and test. This cleaning procedure never fails....

Happy Boating

If carb has been working faultlessly, why tinker with it at all?

Because the are lots of motor morons that likes fingering floats straight when having fuel spills and don't realize that's a needle and seat issue. Carb working fine and carb working fine with fuel spills are 2 different carb's working situations if that answers your inquiry...

You're a mechanic David two sorts in my expeariance one is a must to fiddle and needs to know it's right the other is his motors are sheds but does a great job for others. Joking aside not many AA men out at sea you'll give it a strip down for sure.

Be my guest, that's enterily up to you. Personally if my motor is working spot on and running top, don't need to open the carb to have a look unless like playing being a mechanic or there's proven fuel spills going on while motor still runs good. I know, don't run any motor that way as collected fuel on pan will surely ignite inside cowl and kaboooooom bye-bye.

Happy Boating
