We have just put a Holley 650 spread bore on a 351 Cleveland, had a 600 square bore before, have replaced the dissy, leads, plugs all the main electrical stuff.
We have the timing set on 6deg and have found it stutters on take off, but once your going there are no problems, can anybody tell me please how to eliminate the stutter on take off. Thanks
when you turn it over you can see the fuel going in okay, and the carby is completely rebuilt does a spreadbore use a different air/fuel mix to a square bore?
We used to tune the idle on the 600 by ear but can't seem to do it with this one is there a trick to adjusting the idle mix on a spreadbore thanks
try upping the timing a little more and see if the studder goes away.
