he's talking about something someone else mentioned. But he does have a good point, 2 strokes (the blaster) do burn in different ways depending oh what fuel mixtures and oils you use. That quick silver stuff they were talking about is for low rpm marine engines, definitely not the 11000 RPM air...
I'm not entirely sure about these silencers but some cars start to smell terrible due to the build up in the muffler/ cat. I've never actually cleaned my muffler out before lol
I mean, it smells like a 2 stroke. Most of them smell as far as I have experienced. If yours smells really bad it might be that your running it too rich.
