Sorry!, for the mirrored image, was done on my phone. How to clean your Holley or any other aluminum carburetor with 33% Muriatic acid without spending a ton of money with great results. This process is NOT compatible with all carbs. Do a small test piece first to make sure your carb is compatible with this method. Note: This process will not work with pot metal! (It will turn black) Make sure that when you rebuild your carb after this process you spray a little WD40 on all the bolts, threads and steel parts before installing them. Good luck! I will be posting up my L79 (327) .030 over SBC 11:03.1 CR 331 CI build soon, using this rebuilt Holley 750. Please hit the like and subscribe button, Thanks!
Safety notes:
1. Eye protection
2. Rubber gloves
3. Well ventilated area
4. Dispose of the used acid solution in the toilet, keeps the pipes clean.
