Sundance you have the same problem I had for a LONG time just ask Musky. Your PMS is out to far and will fall out like mine did. I had SVS so bad I couldn't get the carb right. I did the 170 main clip on 4 and pilot 35 and it still sucked. I had to go to a 162.5 main, clip on 3 with a silver washer and a gold washer, Pilot to 37. I ran like this for about 2500 miles and treated for SVS with Seafoam over and over. The plugs I pulled out were nice and white for a change. I had it Dynoed and he said I was way to lean for Texas heat I rejetted to 172.5 main, clip on 4 with one silver washer and pilot back to 35. I had it Dynoed with that configuration and he said I was right on that I couldn't get it any better. I am running that now with a ported stock manifold and Dyna 3000 set at 34A. Putting out 67HP and 98lbs torque. Just something for you to ponder.
