i used that recurve kit, but I cannot remember what springs I used. I DO remember doing some heavy duty reading on the topic before I bought the kit. I had an ignition problem that I solved by installing the kit. All of my other ignition components were working fine. The fatter springs will hold the weights together longer, the lighter springs will not. Do you have some sort of problem that you are trying to correct?
ihave used that kit i worked well i found an old distributor machine so i can setup my advance etc. before that i had piles of wieghts and springs now i just pop it in spin itup and see just what it's doin it saves a ton of time
