Good rebuild kit

March 06, 2012
This kit came with all the things to rebuild the carb in all of its different designs. I have used other Holley rebuild kits and they came with much better directions but with my carb type it was pretty self explanatory.
Yes, I recommend this product.

almost everything i needed

August 23, 2011
I used this for my 56 ford vicky that had a 57' or 58' 2300 holly on it. every thing matched up except the new float adjust, mine must of been an older design where the top screw is built on to the rod. since the replacement was just the rod, I used the origional with the new O ring. seamed to work well.
Pros:
  • Easy To Use
Yes, I recommend this product.
