Title: Setup for a 102c comet clutch 1979 invader 340
Post by: Reevs73 on February 13, 2023, 04:28:47 PM

Anybody have a good starting point for putting a comet 102c on a 1979 invader 340? Son is racing ice ovals with it at 7000 ft elevation

The 440 calls for a purple spring with B weights.  Maybe choose a similar ramp profile with a few grams lighter to start.

Welcome to the site!!  The 340 was very competitive back in the day.  I've run the Comets but never really tuned them.
