Did a weight slip out from under the T bar slot while cap was off? 1/8" may be enough to Sorry T bar probably not correct description.

I just solved an idle issue with my son's truck. One of the primary throttle blades was bent exposing too much t-slot on that barrel. He drives it to work all year, and I suspect he may have had a lean backfire last winter. I initially set the carb up 4 years ago, so I did not expect it to be a...

You need to figure out what circuit you are running on when you feel the miss. are the primaries flowing or are you still on the idle/t slot circuit?

You need too research the T-slot to understand what it does. Lots of good info on the web. As for fuel system factory style tank, 3/8 line to a good mechanical pump for a street car, -6 from pump to carb. simple.

The reason the idle screws no longer work is you're out of range of their operation and into the T slot. The T slot and idle are fed from the same source so as one increases the other diminishes.

Turk, Post # 106. If YOU were paying attention, I made no mention of T slot length....or width.

The "economizer" system accomplishes almost the same thing as a t-slot restrictor, but is not a transistion slot restrictor. It is arguably (and I think practically too) a more effective system because of how it works.

If you were paying sttention…original Holley’s don’t have that long T slot. They generally do not need T slot restriction.

Ok, that’s another rule of thumb as far as T slot exposure. I start with a square slot and then open the throttle to get it to idle. Once I finalize everything I verify the T slots are not open so far that the mixture screws don’t work. There is no tuning magic in T slot exposure. They can’t...

What is the idle timing? Depending on what the cruise rpm is, you might be cruising on the T/slot.....or the main system. Am I reading this right: best idle is 1/4 turn out from seated? That suggests too much T/slot is exposed at idle.

The reason I wasn’t positive if that was the case is because the exposed slot was about 0.050” making an approximate square slit visible as seen by the picture I posted previously. From what I understood this was perfectly acceptable BUT I am not running a stock engine. So maybe other rules of...

Yes, the intakes rockers are offset on the TA's. Without the valve Trane, look for the intake pushrod slot being egg shaped.

it's possible to shorten the slot itselfs Note that secondary side are usually higher up but not always. This guy went on a journey from greenhorn to a carby smarty. :) https://www.tapatalk.com/groups/racingfuelsystems/transfer-slot-lengths-t1285.html#p11866...

I couldn't stay-up to watch the O/T, but sure am glad the Oilers won!

Yes

Totally understand what your saying, but I think it's getting too much air, not too little. That's why I asked about t slot exposure. I'm not completely stuck on them, but really looking for reference.

I looked up the t-slot, that’s the little opening where the throttle blades are. A long time ago I had it adjusted properly and I’d say it’s probably not adjusted correct anymore Drove the girls to get donuts. Fires up first crank when cold, at the donut store it seems starved for gas. Crank it...

I believe that this is the area where the transition is tapering off and the mains coming in. This last change of bleeds seems to maybe have broadened that area. I may just go back to the previous tune and retest.

Also, to add to the carb “t” slot info. You changed this engine drastically from stock. Don’t expect it to run or idle like stock 100%. Many times after a cam swap people want this engines to act like stock. Low vacuum from a lopy cam will mess with your idle and the transfer slots will not...

The T slot. Above the idle mixture screw holes, where the holes exit in the t/bore. The slot is usually just above those holes. A rectangular slot, varies depending on carb but often 0.025 to 0.035" wide & 3/16" to 1/4" in height. They are part of the idle cct. With the engine idling at the...

Its big because that is just meant to be a passageway, not a restriction. The outer passage goes to the idle port and is restricted by the needle valves (idle mix screws). The inner passage goes to the transfer slot and is restricted by the slot width, depth, and amount exposed to manifold...

Yep! 15x7's. I wouldn't try 8" wide. Too close with out trimming.

I had some slot mags on my car from back in the day that worked with some pretty wide bias ply tires; don’t remember the specs. When I went to radial T/A s I had to change wheels. I found 4 1/4 to 4 1/2 backset centers the wheels in my 1970 dart.

I definitely have .040 or less of the t slot showing

He has the idle screw backed ALL the way out now and it's idling at 1000. He clearly said his mixture screws work. If he drills holes in the throttle plates, that will make his problem with the high idle WORSE. You need to read what he's posting. Do I need to call your wife and tell her to slap you?

The manifold vacuum advance is consistent with AJ’s theory about the T slot exposure. Float level is also worth looking into

If you have 0.040" [ or less ] of T slot showing at idle, then you do not need any [ more ] bypass air.

to continue, measured my T slot orifice and was shocked. The pic shows a 060 and 055 pin gauge in there. so it's .115 or so. Seems pretty friggin big if ya ask me, but who knows. Since I'm so rich at cruise RPM, what size should I restrict it to? No idea where to begin.

As a general rule, I don’t read the bullshit you post. As wrong as you are and as often as you are wrong there is no reason to read what you post very close or even at all.
