Just to get you off on the right foot, there is no such thing as an 80cc engine, they are all 66cc, hence the 66/80cc the ads say, it can't be both ;-}
$250 is a pretty slim budget unless you go with a used bike.
A quality engine kit like a real Grubb Skyhawk GT5 66cc is ~$150 http://www.bicycle-engines.com/2-Stroke-Engine-Kits/
and worth every penny of it.
Whatever you use for a bike I recommend it NOT be a $100 Huffy, you need a good bike with good brakes before you throw an engine on it.
