        That normally shouldn't be needed if all the rubber/etc is in good
shape - water shouldn't be getting in.

        The problems described sound like one of: too-thick carb oil; carbs
that need a rebuild; badly adjusted or improperly used choke; or maybe timing
wrong or a vacuum leak.

        Carb oil is one of the easy things (and you can check for split
diaphragms while changing it).  TRF and others sell carb oil; others swear by
Marvel Mystery oil; I've used 10W-40 and 5W-30 as well in the past.  You may
be leaking oil too.
