Lucky 7 is a "wicking" sealant.... meaning run it around the seams you want to seal with the engine ASSEMBLED..... dont get it anywhere near the internals of the engine or it will "wick" its way inside and make a mess. The video is the correct way to fill your engine will sealant lol typical mag editors mis-using yet another product........That little bottle will last you several years
+1 I couldn't have said it better myself.
applying Lucky 7 sealant to ANY internal components is a bad idea, and is not recommended.
After the carb is set to the correct angle and pinch bolt is tight, I seal around the carb base, and pinch bolt ends, I'll also neatly seal around the High speed needle assembly, after the nipple is tightened down to the angle I want. As Tony already mentioned its a wicking sealant so it'll easily work its way around and into the tight areas.
With all due respect most silicone has a bad reaction to nitro fuel.
