Chech your reeds.

Hello all. Have a old build jd jug with 596cc 10 mill. Yes 596ccs has 39 pkw s, previously added. It’s a panini build with unmarked duncan pipes and cascade silencers.. Any suggestions for the best tune? Timing? Jet sizes? Previouse owner had stock 39 mm jets and timing was retarded to six deg adv..It kickes backed at starting and lacks top end. I’m thinking adv back to 10 deg and run 60 Idle and 164 main jets. It’s supposed to be a 120-130 hp build. Suggestions please.. Thxs
