Why It Matters
The hungriest big-displacement builds drink past everything smaller, leaning out at full throttle under load where lesser jets give up. The 170 main jet is the richest in the 40K, Kadron, and Solex range, a 1.70mm brass orifice for the engines that ask for all of it.
The 170 is the largest size in the 40K, Kadron and Solex range, for the hungriest big-displacement builds with the highest fuel demand.
Installation Notes
The jet is threaded brass and swaps with a flat screwdriver. Fit it in place of the existing main jet in your 40K, Kadron, Brosol or Solex carburetor.
