Wal-Mart has nothing like Lucky 7 sealant. You do NOT have to take your engine apart to apply Lucky 7 sealant either. It is a wicking sealant so it will work its way into tight areas and seal them off. I seal around the carb base, pinch bolt ends, back plate, and high speed needle assembly while everything is still in place and tightened down.
Go to
Lucky 7 RC and pick up a bottle. You wont regret it!
