holley carb
I have a 300 i6 bored .030 over has a offy cseries intake and a holley 390. It idles very nicely, and as long as you give it gas it runs just fine. but if you want to let off the gas and just cruse down the road at any speed it wants to run rough (spuddery). What can i do to fix this.
The motor only has like 6000 miles on the rebuild, i also have put new spark plug, cap, rotor, and wires only about 200 miles ago.
Thanks
daniel

Call the Holley tech line. 1-800-holley5
Not that the people here would lead you wrong, but it's free to call the tech line and why not get it straight from the horse's mouth. Just be prepared to describe your problem exactly and your motor specs and whether your carb is 'stock' or not. Good luck
