Sounds like a sticky needle valve in the carb, sometimes sticking in
the open position, other times in the closed position. It could also
be combined with aged or cracked gaskets in the carb. At the times
that the needle valve opens the gas would leak out. Solution: Overhaul
the carb. Also check for cracked/leaky/kinked fuel hoses.

Sounds like a bad connection at the solenoid or a defective solenoid.
Solution: Remove each of the wires, clean thoroughly and reconnect.
Your solenoid case may also need to be grounded, so clean the mounting
bracket or ground strap if there is one. If still no go, get a 12v
test light or meter. Check to make sure that 12v is being applied to
the small wire on the solenoid when the key is turned to start. This
should in turn close the solenoid and allow 12v to flow directly from
the battery to the starter. If you don't see 12v on the small wire when
the key is turned to start, check the ignition switch and wiring. If
you've got juice at the solenoid but it will not close then suspect a
bad solenoid.

Are you asking for advice on how to fix these problems, or just looking
for a good shop to take it to for repairs? Neither of your problems is
anything major that you can't fix yourself if you're reasonably handy
and patient. You should also be able to save quite a few $$$, because
most dealers will soak you for big bucks for a carb rebuild or a new
carb. The electrical problem is most likely so simple there's no reason
you shouldn't at least try it yourself. If you have any doubts, try to
get a friend who is familiar with this stuff to help you out.
