Re: Honda 2hp 4-stroke
As above but WD40 is your friend. Spray everywhere around the powerhead but especially the electrics.
The old plug will do fine when dry.
Make sure you are getting a spark before you make any serious attempt to start it.
I have helped with several drowned OBs and they all ran again. Mind you they were 2 sts.
BTW do not be surprised if the ignition packs up in 9 - 18 months time.
