    225 pro xs running bad after warm up

    Serial 1b540866 I have been experiencing a sluggish mis while running and also showing up in a dirty prop which is normally clean running dons cocktails. Today I finally figured out it runs perfect first thing in the morning then starts running bad as the motor heats up. Any ideas what could cause this. I have ruled out coils by trouble shooting them one at a time with a new one. I'm thinking plug wire or maybe a bad plug although they are new.

    What is the motors temperature sitting at idle speed?

    Perform a spark test as the problem is occurring. Electrical problems start sometimes after the component warms up.

    Sure....You can only troubleshoot as the problem is occurring though.

    Would it be possible to narrow it down by reading the conditions of the plugs? Since my prop is sooting up doesn't that mean one or possibly more cylinders are not firing right?

    Soot in the prop area doesn't mean the motor isn't firing correctly.
