Just spent 3 days on the boat, running my relatively new Honda EU1000 generator. Today I try to start it to heat the oil for an oil change and it won't start. New spark plug fires when grounded to engine. New gas, and the carb is clean inside. Finger over the spark plug hole shows good compression. Starter fluid squirted down the carb does nothing. I have fuel, compression, and spark but not a hint of it trying to start. Anyone out there have any ideas?
