tuning a g1 comet clutch

[drifting g1]

New to the forum and did a lot of searching and still a little confused on the tuning of the comet clutch. I have a G1, doing a new top end now and wanted a little better take off. Doing a burnout in gravel and some wet grass would be great!! Right now the motor barely spins and the cart takes off. I have not taken it apart yet till I asked on here if worth the work. Can i just shim a spring, if applies to this one and not just the older style? The weights, the lighter the faster in engauges? The heavier the weights, the higher the motor revs before engauging? What does all 9 weights weigh, and where should I be to do what I want? Thanks for the help, Tony.
