This is a 15cc bottle of Lucky 7 RC Air Seal Engine Sealant. Lucky 7 Air Seal is a fast drying, wicking sealant that does not require engine disassembly! Simply apply it topically to the carburetor neck and backplate seams, and let dry. If your nitro engine has an air leak, it can make the engine run erratically. To avoid this it is a good idea to seal up the carburetor around the neck and needle valve assembly, as well as the backplate before an air leak develops. Dont roll the dice with your equipment, get Lucky.

NOTE: 30 - 60 minutes dry time is recommended before use. Surface must be clean, and oil free prior to application. It is also very important that the bottle be stored at room temperature.

MUST MUST MUST HAVE!!!!! This is one of the cheapest, most under ratesd items in the RC Nitro world. YOU CAN NOT HAVE AIR LEAKS and expect your engine to run smooth, idle without flamming out or have / keep consistent tunes on your engine. THIS IS THE BEST SEALANT out there. you put some on and "blow" it around the various parts of the engine. it's NOT A GASKET, it is to be used as an outer type seal. it pulls off fairly easy if you need to adjust something, then just add some more when youre done to seal it back up.
I cant stress enough how important this product is to the Nitro Engine. AIR LEAKS ARE BAD and this product eliminates air leaks.

use this product on the High Speed Needle around the fuel needle and base of the needle assembly, the carb pinch bolts (both sides), and where the carb meets the case, and the crank case backing plate. you can seal about 7-10 engines on one bottle.
I also use it around my fuel filter and my exhaust cooler.
if you find a product that works any better than this does, write me an email and I'll buy you a bottle of whatever it is and I'll get myself one.... but trust me, I aint worried about someone finding a better product than the Lucky 7 sealant. it just doesnt exist out there today.)
