The service on the carb was really quick.
I called Holley and told them their carb was f****d up so they said call Summit and send it back.
Summit was great they sent me a new one before they had the old one picked up.
Anyway there is a very noticable difference in performance from going up to 700cfm from 650cfm and now my Vet actually idles a lot smoother at 800RPMs

The only problem I now have is my accelerator cable is hanging up somewhere and somehow.
I put the pedal down in 4th the other day and it stayed down, scary moment or two,
wound up turning the key off and took it easy going home.
I think the cause might be because I put a Holley 1/2" spacer under the carb, it is the kind with 4 holes in it.
The secondary butterflies might be rubbing.

Stay tuned,

Was the new Holley jetted the same, same secondary spring, and have the same power valves as the bad one?

Just wondering since the 50 extra CFM shouldn't make much difference unless the engine is heavily modified.

 

I guess it wouln't make that much of a difference but remember the old never worked the way it should have.

The throttle plates could be hanging up on the spacer or they could be hanging up on the carb base plate. Before you remove the carb to check this, remove the air cleaner and have somone push the pedal to the floor. Look at the cable for bends that are too tight. Then have them release the pedal. If it sticks, gently touch the cable to see if there is some play at the connection point between the cable and the carb. If there is play (you can wiggle the cable without the carb releasing from full throttle) then it is not the cable. It is either the spacer or the base plate.
