Holley/Demon Carb stumble

We all know pic are hard to read a plug. but i haven't pulled a plug in a while so i will do that.
think i still have one new plug so cutting off the threads of one should be now problem.

Explain to me again what "T slots do and where you install them and what it accomplishes.


The T slot is where you get fuel when you transition (or transfer) from getting fuel from the curb discharge port and getting on the booster/main jet.

After this weekend I’m going to start doing more 1:1 linkage carbs again. It keeps you on the transfer slots longer. And they just drive better.

They are installed in the main body where the metering block bolts on.
