Thanks for the reply, yeah it was from the ebay guy. I believe they were 48 jets, They may be 46 but I have to check he only sent a paper stating the Jet size nothing else really. I am not sure of the powervalve size and as for the Mixture screws I have been adjusting them so I would say about 5 turns out I think. The timming is at 8 Degrees BTDC right now and I am in Southern California in the inland empire area, about 30 miles inland from Los angeles.
Thanks for the help.
