" I winterized the engine w/ fogger, spray oil, fuel stabilizer (which I run year-round anyway) last November. On Saturday, I took it down to the lake. It started right up & ran perfectly for a 30 minute test cruise, I took it through all RPM ranges & to WOT, no problems.
Today I pulled the plugs out, expecting to find carbon to clean. The top two plugs were almost dry, with just a touch of black on the electrode. The next two down were a little wetter, the bottom two were oily. The insulation on every plug was fairly white.. the top two drier plugs had some specs of rust on them - that concerns me, but it's been a long winter.
Is 30 minutes just not enough to carbon the plugs up? Does this sound like it's running lean? I'm a little hesitant to rebuild the carbs when it's running so nice, but is that warranted just by differences in the plugs? Should I go ahead & richen the top carb's low speed jet, or should I run it for another 20 hours & then take a look? What do you think? Thanks for any/all replies,
