Success, thanks Joe/Ted 😊

Thanks Joe, the carburetor is installed. I’m going to spray it with WD 40 and let it sit for a while. I thought of filing down the sides of the plug and putting a wrench on it but want to try easy first. On second thought I think I’ll use a hacksaw blade and deepen the screw slot then try the screw driver/wrench.

Use a large flat blade screwdriver and an adjustable wrench on the shank of the screwdriver.  You may want to mount the carb first so that you have leverage.   Use teflon tape on the threads of the new fitting.  Joe-JDC

Ahhhhh.. Got the parts but can’t get the vacuum plug to budge 😫

It came with the carburetor from Summit.  Check with O'Reilleys, Advance Auto, Auto Zone, or even Lowes.  They have a rack with an assortment of brass fittings.  Joe-JDC

Joe could you tell me where you got the vacuum booster threaded nipple for the 1/2 ID PCV hose. NAPA only has a 1/8 to 1/2” adapter which adds over two inches to the assembly.

It's the same direct vacuum available at both the front and rear.  The Summit carbs do come with the 1/8" NPT barbed fitting to go into that back hole for those that choose to use that location.  My own preference is to always pull the vacuum for a PCV valve at the rear of a four barrel carburetor when you have a choice.  This keeps disturbance in air flow away from the primary throttle bores. For the Y with the PCV valve located at the back of the valley cover, it’s a much cleaner look with a shorter hose.

Thanks for the coil picture. The tag on the box says it all - looks like it's a  late Ford Duraspark application.  Thanks..............

Yes, I do not have power brakes, and this is so much simpler.  Does not affect idle adjustments.  Did this way on a couple of dyno testing engines, and no issues with this system.  Joe-JDC

I noticed the PCV hose is connected to the rear of the carb base. I have a Summit 600 CFM which has a PCV connection in the front, it has a screw plug in the same location as yours. The installation instructions say that where you have it is a power break vacuum port.
