I`m putting this here in the Lounge so`s I don`t Hi-Jack another post. Squish or Squeeze as we called it in Kart Racing was the answer to more HP. (along with more Nitro) .060 off the Squeeze was the norm. Usually?. When the Kart came back to the pits and looked like Pic 1 there was a problem. Pic 2, the diagnosis is that the engine vertically separated from too much compression. Pic 3, the solution is to buy another engine and girdle and sandwich it together. This eliminates the vertical aspect and opens up to the horizontal explosion. While your at it go ahead and remove .090 Squeeze and add more Nitro. Works every time. Well sometimes it does.
