We include 2 clean out plugs for the metering block. Carefully drill out the old plugs (don't make the hole too big), clean out the holes well. The old check balls can be used unless they are corroded. Tap the new plugs in, only as far as the old plugs were. If your block looks clean with no corrosion then you would be advised to leave it alone. Just clean it.

I am happy to write this review. I recondition a good amount of units for a group of my clientele. This particular kit for the Holley 1904 was outstanding in quality and fitment. I would happily buy this kit again for another Holley 1904 refurbishment.

High quality rebuild kit for my 1964 scout, had a question on the needle and seat and when I gave them a call they were more than happy to answer my questions. Would defninately buy another kit through them in the future

I ordered this kit for my old International pick up and received it in just a few days- great service. I checked local auto stores for this kit and found some at twice the price- great service. I installed this kit into my old Holley with no issues with perfect fit all the way around-great service. I downloaded the Holley 1904 repair and troubleshooting guide from your website and now have that as a valuable resource in my shop-great service. 5 star rating from a great service!

Fast, fast delivery! The 1904 Holley kit worked well, especially the cork float bowl gasket, I'm hoping the gasket doesn't breakdown as fast, from today's gasoline as other cork gaskets I've used in the past. Very pleased with the product and service.

Thank you for the good service and your videos were helpful. I used the heating trick on the main body which I never would have thought of or attempted without the video. I did distort the body some so maybe too much heat but worked out. This is on an IH truck I am restoring so may be a while before knowing if I did good. Didn't realize when ordering the kit that you were somewhat local to me. Thanks Dennis
