I added a set of Webers to my big block in 2015. At the time, there were four of us in the US struggling to get our systems setup. Philippe Riobe in Miami, Tim Gillespe in Eastern Tennessee, John Hirasaki in Redondo Beach, CA and me in Saint Louis. None of us close enough to physically help each other but we did share a lot of information back and forth.

Not sure if John is still active or not, he was on this forum as "jhirasak". Tim has since moved on but I do have a copy of his notes that you are welcome to.

Philippe is still driving his with the Webers. I was able to get mine sorted out and played with them for a couple years till I came accross an opportunity to switch to an EightStack system. Webers ran ok but were always problematic with air density changes or altitude changes. I was constantly running into this and the fuel injection solved those isses.

The 48IDA's were really designed to be operated at full throttle most of the time. They really don't like idle or transitioning. But with persistence, they can be sorted out. They are extremely critical of fuel level - even to the point that the angled ones from a big block require a different level setting than those that sit vertical. The relationship of fuel level to the holes in the emulsion tubes is what will solve or create the idle and transition problems.

You might try to track down John, he's at least in California and could possibly be within driving range.

I'll be happy to share anything that I have to help you out. Webers can be managed, but it is a challenge and not for someone not willing to constantly tinker with them.

I am not able to attach Tim's notes to this thread. The PDF is 1.6Mb and this forum will only allow a 40k file. Send me your email address via PM and I'll send you a copy. I've attached a picture of my Weber setup - pre-EightStack
