need help with invader 440 clutching
Kal k:
Hi, I just bought a 79 invader and am planning on taking it to some drags. As of right now I got the motor out and going through it plus doing all the seals. Gonna start by making sure it's running good. I'm planning on putting a 102c comet clutch on it and was wondering what spring and weights a guy should get to make it engage in that 4500 - 5000 rpm rang and rev out at 7900 - 8000 rpm. I know this stuff takes lots of trial and error to get it perfect but was hopping someone could point me in the right direction. Thanks

This is the recommendation's from Comet for a Deere Liquifire. Very similar engine.

Use the Liquifire 436. B1 weights are hard to find. N weights will work.
This page has lots of info on the comet clutch.
