Manifold slots, i keep...
I was the Valedictorian of my high school, graduated from automotive school, and graduated from the most prestigious public engineering school in the nation, Cal Poly, San Luis Obispo, where I received a Bachelor's degree in Mechanical Engineering Technology.
All the cheap stuff is junk, especially the needle and seat assemblies, and you will not save any money in the long run! Replacing the primary power valve with a plug: If you have a carb with a normal system where the mixture leans as you turn the screws in, then when you screw them in almost to a light seating, the engine should die.
You can't just throw any jets in there because you think it needs to go one way or the other. In Holleys, there are two pump check valves: Don't use adapters, either!
Start stepping the jets up or down, one step at a time, and drive the car around for a day or two. Rear track increased with wider swing axles to mm. There is an idle circuit in the rear barrels of your Holley, too. You always want to go a bit rich, as excessively lean mixtures will cause damage to your engine, create pollution, and give you bad gas mileage and performance.
BUT, most if not all of the parts in the kit are identical to those in a number Holley kit, the very common cfm 4 barrel. The performance may not be optimum due to manifold slots strength or restrictions, but if the jetting is close for one, it will be close for the other. Remember, your eyes are using this data, and if it stops for a while, no harm is done! The readings you'll get once the sensor manifold slots heated up will be from 1.
This is most likely due to a bad float valve, bad float, or excessive fuel pressure. If your link is too long, the secondaries won't open all the way, no matter what spring you have installed. There are several ways to fix this problem: If using a manual choke, remove one screw at a time and install the choke cable holder.
Replacement Parts for the MGA and MGB
If the gas just pours out all over the place, shut the engine off right away before you start a fire. Rubber parts, including float valves, accelerator pump diaphragms and power valves, can dry out and stiffen.
Here is a pic of the vacuum passage going into the carb.
The opinions expressed here are my experiences, and your experiences may vary. Bigger front brakes drum brake model.

Graphical interpretation of these systems: There is no way on this Earth that I can give anyone specific recommendations for jetting, power valves, or accelerator pump settings, because only YOU can drive the vehicle! The transition circuit supplies fuel between the idle and the main metering system. Large black knob added to vent window opener. In order to set the floats on a Holley with externally adjustable floats, remove the sight plug with the engine off.
