    I did have it apart. I used the Renew Kit 3-888: https://www.holley.com/products/fuel...it/parts/3-888. I'm not sure which jet was in it (assume it was stock), but I replaced the PV with the one in the kit. The cam was the orange cam. Going to order the cam kit and try your suggestion. I would rather it run with better fuel economy then the most power. It's not a race car. Again thanks for your help!

    Sounds like it is stock, 61 main, 8.5 PV, 31 nozzle, orange cam.

    Any other adjustment is via a number drill, bent wire tricks into idle feeds, etc.

    You may find trying the pump cam in position #2, which offers a slight volume increase may help in finding the cam the engine likes.

    I used a blue cam in hole #2 with a 31 nozzle and it was about 90% correct. I think going up to a 33 will do the trick, but I could live with it as is. Thanks for your help Gary!
