Upgraded to the new ball seats and ethanol resistant gaskets. Need it here in the Fort Worth, TX area as we have a 10% blend in our fuel. Reamed out the shafts and installed a new set. Specifically one for the primary and one for the secondary. There is a difference. I have the stock fuel pump regulated down to 3.5 psi which has resolved any blown out seat issues. I have had no issues in the 6 years I have been running this set up. Had '97's before but always had stumbling and had to constantly adjust the setup. The '94's have proved more reliable. I used a good quality MAC vacuum guage to set the vacuum and moved back and forth until I had maintained a steady reading. Holds a good 16-18 hg. vacuum. I have had good luck with Vintage Speed out of Florida on my parts and they have been helpful on information. But as a HUGE supporter of the HAMB the Holley '94 social group has been a big help.
Pics of my setup below. Needs a good cleaning. But hey, I love driving her!
