Reply To: I’m absolutely bushed

Thanks crosbyman, mas, Cajun, fleetwin, Dan Umbarger and rudderless for your replies……..much appreciated.
Reading your replies I can see unfortunately that I slipped up badly in not explaining that the motor is a 2 stroke Yamaha and not a 4 stroke,
so please accept my apologies for this oversight.

I can see now that I should have put the model number ……..would have made things a lot clearer and saved you time and trouble. Again my apologies!
Here in NZ we have lots of small 2 strokes and in fact you can still buy new small 2hp 2 stroke Yamaha outboards as well as other brands.
How much longer for, remains to be seen. I think Tohatsu is the major manufacturer for Mercury etc these days.

The motor model number is 2CMH.

I would like to add that the fuel tank and line has been thoroughly flushed out and as I mentioned previously, every component of the carb has been taken apart and cleaned and then blown through with my compressor.

We feel that it be a fuel problem because of the way the motor just peters out when you get to the idle position..
We have also tried another (new) sparkplug……..no improvement.

Any other ideas will be much appreciated.

Thanks very much once again.

The carb doesn’t have any butterflies in it’s construction, only the cylindrical piston carrying an adjustable brass needle.
