I'm guessing that 10 pack is about the same cost as a single one in a mower shop, or at the very least represents way better value than one or two at a retail outlet.
EDIT: I was only going to go ahead with trying a new carburettor if the cost is below $20. Getting the gaskets will blow that out. Maybe it's just not worth it, especially as this engine is likely to be Chinese made, being on a Tornado base.
