[QUOTE="BrounHownd, post: 482229, member: 30222"] Thanks for all of this info! I did sync both the carbs and timing linkages according to the manual the first reply provided. Also, yes, checked TDC for sure! As to the CDI, I don't doubt what you're saying, but what else can I say? I put the multimeter to it per the manual and every resistance measurement from the trigger wire was WAAAAY higher than the specs in the manual--and the boys that wrote that said if they're off to replace the component. Yes I cleaned the connectors and the probes. I've heard about the 100 and 50 oil mixtures too--Mariner manual says 50 but I've also read similar motors with a Yamaha badge are spec'd at 100. Anyway, had it out on the lake last Friday and it's damn close to being OK, at least in my opinion, for a 40 year old motor. It'll do for now until I'm on to the next project. [/QUOTE]
