My 1985 90 hp Yamaha model 90ETLK stalls at idle , or when putting it into forward or reverse.<br /><br />The boat does not get used too often and sits idle for weeks at a time. The present gas (in a new gas tank) has been in there for 3 months.<br />I changed the plugs as a precaution and always use Yamaha Ring Free in the tank.<br />I notice that the squeeze bulb does not get too hard when I prime it. <br />If the carbs are fouled , what additive or spray can be used to clean them?<br />Any suggestions?
