[QUOTE="Fitz, post: 117098, member: 20906"] I have an older742B with a Mitsubishi. It started missing on higher rpm and is getting worse. Thinking lack of fuel I’ve replaced fuel pump with electric, all fuel lines to the tank pick up filter. I did a cylinder compression check and all were the same at 145#. I noticed the number 2 and 4 plugs were very light in color, 1&3 were as they should look, why??? Also I adjusted the timing a bit while running and when I put hand pressure on the cap the missing stopped, rotor??? I’ve been chasing my tail for a week on this. Anyone have an idea? One more thing , since this has gotten worse the last month the governor wants to pull the rpms down from high to mid range at max. [/QUOTE]
