i have a 30hp johnson '91 model. it seems to always run very rich. if it idles for more than 3 or 4 minutes it loads up. there seems to be an excessive amount of oil or gas coming from the exhaust when idleing. i can see it come up out of the water. <br />things i have tried and checked:<br />1. kit for carb.<br />2. smaller low speed jet<br />3. new ignition coils<br />4. checked fuel pump diaphram<br />5. changed gas to ensure it was the right mixture<br />6. carb linkage<br />7. made sure all fuel lines were connected.<br />any other ideas would be greatly appreciated.<br />thanks likearock!
