Frequently asked questions

A starting value of 100 usec can be used, but the engine should be run up to 3000-4000 RPM and timing checked such that it matches the commanded value. If it is lower than commanded, the Inductive Delay should be increased, if higher, the delay decreased.

Rotate the distributor housing until the rotor contact is pointed at the black crank position sensor. Both the cam and crank LED should be illuminated. Slowly turn the housing clockwise or counter-clockwise until the Crank LED goes OFF, then turn it back until the Crank LED comes back ON. This will position the distributor close to where it needs to be. Install and snug the distributor clamp down at this point.

The distributor comes with a hardened steel distributor gear that should be compatible with all applications, other than a billet steel camshaft. If a billet steel camshaft is used, a bronze gear is recommended. (See P/N’s at end).
