    02 Optimax service question

    I've got an 02 225 optimax with 740 hours. I had it tune up and fuel pump rebuilt. Now it is harder to start and when i put it gear it dies? but if i start it, put it neutral rev the throttle a little then put it gear it does fine. Is there something I can have done to help this dying problem?

    Thank you EB

    Re: 02 Optimax service question (emerson biggens)

    My first list of suspects would be:

    -Improper or damaged spark plugs (SHOULD be IZFR5G spark plugs ONLY).

    -Improperly rebuilt pulse fuel pump (improper stacking of components, perforated diaphram(s), etc).

    -Loose or improperly connected spark plug wires.

    If the pump was rebuilt improperly would it still run fine at high rpm's ( which mine does )?

    Thanks for all you do!

    It might.... depends on specifically what was wrong.
