Installed the CHT probe on the #1 cylinder inside manifold bolt by first removing the bolt. The probe provide did not have a large enough hole to fit the bolt. Took a copper washer of the correct size and soldered it onto the probe. Drilled out the center hold to the correct size for the manifold bolt. Added a small aluminum washer per the installation instructions and mounted the modified probe to the manifold. Tighten the bolt to the same level that it was when removed.
