I hate to be a buzz killer but the lesson
here is how to evaluate a motor to determine
if it is worth investing any money in.
The pictures seem to indicate that it is so
corroded there is a hole through the gas tank.
This would indicate to me its is not.
As it turns over it may have parts that
are still good. Also an opportunity to
learn technique in getting these things
apart without braking stuff. That looks
like its going to be a real challenge
on that motor. My suggestion would
be to look for another in better condition
that may need parts you can salvage from
this motor. This not a motor you would
want to invest much money in IMO.
