yamaha 2 stroke outboard oil

[graham]

I am using a 4 stroke now .but used small 2 strokes for decades on cheap 2 stroke oil. Have to admit to needing to clean the carb about once in every 5 seasons other than that no problems.I allways run off the fuel in the carb until the engine stops which must help.

I would be inclined to clean the needle with some very fine polish like Brasso or even finer .... polish it to shine ....

Take a pipe cleaner and see if you can similar clean the opposite part .... get them squeeky clean ...

then try fuel through etc.
