Mine won't start on wet days either! Wish you had an answer on here.

Well it could be a number of reasons why it won't start on wet days,

here are the common reasons.

wet starter connections, wet or damp solenoid, wet or damp alternator connections,

water or dampness in the fuel injectors, wet or dampness or even water in your spark plugs.

also check the carburetor for signs of dampness and water.
