:huh: I have '89 340 EC with twin Merc 454. I had replaced plugs and wires last year on starboard eng--cap and rotor this year--started out fine this year but have now devloped the smell of raw gas in the exhaust--(I changed the cap and rotor after discovering this issue). Max RPM has been reduced to around 3100 plus a slight shake when under power (assume it is misfiring)---it has been suggested to rebuild the Rochester Quadrajet carb--Any Suggestions or other trouble shooting tips? Has any one else run into this?
