  1. Hey all Seeking a little advice on tuning the Holley on my ute, ive been threw 2 webbers and cracked it and threw on a redline manifold and a 350 holley, I put a fast kit threw the carb and put 57 jets in it ( they were reccomended to me) and a 6.5 PV <-- ( witch i think needs changing)

     

    Now it runs and idles fine, but has a flat spot in it near 1/4 throttle Right when the clutch grabs and you go to give it abit more the dead spot sits right about there. ive had a vac gauge on it and it sits just under 20 at idle, but thats with the mixture screws only about 1 turn out ( maybe less) from being fully seated witch dosnt seem right to me, but if i open it anymore it looses vacuum and starts sputtering threw the exhaust, when its at the highest vacuum setting its allso really gutless more so then it was with the webber.. cars still running the EST witch could be my problem?

     

    maybe a squirter size change may help me out but unsure on that most people have not seemed to mess with that ( from the threads i read) i know the Carb use to be on a speed way motor had 68 jets in it when i got it.

     

    Motors stock as a rock besides the holley

     

    ive done a fair bit of digging and seen some threads around but all i found seems to be the opposite with everyone having the mixture screws nearly all the way out to get it to run right
