The Friday update: The vacuum fitting is done! After talking to a couple tuning buddies of mine the concensus was not to add a hole, no matter how small, at or near the bottom of the venturi or from the side for that matter. My fears of fuel build up in the tube was agreed with by all. I ended up with drilling out a staked brass plug in the hot start system, which is not installed on this OEM carb, and installing the stainless tube there. Even if the hot start was installed it would still not cause a system problem sharing the port. It ends up right in front of the slide cap so it's almost exactly where the BST fitting was. I'm pretty sure even the stock vacuum hose will be long enough to reach it. So, tonight after work I do the install and my first road test! Pictures are coming!
