Back on 9/11/02 I posted a question about fouling plugs at idle with a newly rebuilt Grey 135. Since then I have dismantled both carbs and reset the float setting and main jet to factory settings.I still build up a considerable amount of carbon on the plugs after a 10 minute idle through a no wake zone. If my main jet is set too rich which way would it have to turn to lean it out? It is set at 2.5 turns per factory. Both chokes are fully open.Thanks for any help.
