Hello:
I have never seen the Quick Fuel carb up close, nor have I worked on one. I tried to contact the manufacturer to determine if the Percy's adjust a jet will interchange with a Quick Fuel Slayer 600 cfm vacuum secondary carb.
Percy's did contact me back right away and they stated that they did not know and told me to contact Quick Fuel....Quick Fuel I sent an email at the same time over the weekend. They seem to be a little slower in a response...So, what difference is there from a primary metering block compared to either the 4150/4160 Holley carb? Anybody know, or have installed a Percy adj. jet into a Slayer carb?

So, unless I here shortly from them, I will order a new Holley instead, this Fri.
