    RATS :eek:oooh: My 1990 30 HP Evinrude Tiller Style is coughing and sneezing as she runs. Runs good for around 10 seconds or so then starts doing this and dies. Tried some seafoam in the carb, had put some in the gas tank before winter. Also tookout plugs and shot some down in there also. Let it set for awhile. Started right up but again around 10 seconds the coughing and sneezing starts and she dies. I did run the motor till it died before winter storage to remove the gas. Gas Tank is 3/4 full and i did put fuel stabilizer for over the winter storage. Shook tank good to mix oil again and added new fuel filter before trying to start her. Any suggestions??? Ordered a carb rebuild kit already hoping thats my problem but not sure. Don't want to start a guessing game on her. Thanks for the help.

    Is the ball on the fuel line staying hard or does it get real soft and collapse. You might have a hole in the line somewhere and sucking air that would do it! You might just have to get the carb cleaned out and rebuilt. It wouldnt hurt.

    I'm an armchair mechanic. Here goes:

    1 get some new gas. burn the old stuff in your car. test.

    2 sneezing means the fuel/air mix is lean. turn the idle adjustment out 1/8 or a turn or something and test.

    Sounds like to me that old corn gas has had it's way with your fuel pump, try this with it running pump the bulb real slow and see if it starts running better, if so it's your fuel pump, the new fuel pumps from Rude are corn proof but they aint cheep. I have a 1988 15 hp doing the same thing a couple of weeks ago.
