Reply to "Holley carburettor adjustment needed"

Thank you for all these leads.

I have a BlueThunder "Pantera" manifold and so the carburetor is horizontal. There is a half inch spacer.

I set the fuel pressure to 6 PSI and checked to make sure the fuel wasn't overflowing through the level hole. As I write this I realize that I only checked one side, I'm going to check the other.

I find it hard to imagine that the carburetor is the only one responsible for the countless backfires.
I modified the advance 10 times in both directions and it doesn't change much.
I will measure the compression, if a valve is no longer tight I will detect it easily.

If everything is good, all I will have to do is try with the old carburetor.

I purchased this carburetor along with several other parts from an Australian supplier. For certain parts he clearly told me that they were Chinese equipment, not for the carburetor which he assured me was indeed a Holley. Have you heard of Chinese copies?
