Yeah, great. But this forum is supposed to be about free exchange of information and ideas, and when the conversation gets shifted to private messaging because of the leg humping ediot, it doesn't really serve that purpose anymore. Maybe the OP's problem gets solved, maybe we'll hear about it, maybe we won't.
it as not be resolved I have been intouch with the builder my fingers are crossed that he come thru with what he has told me. I will say i hve done everything I can to make it run this past weekend have completly measured and pn gauged this whole carb and I suspect its def set up incorrectly for my application.

The OP has a golden opportunity to learn here. He’s got one carb that works and one that doesn’t. He owns pin gauges. Why not duplicate the calibration out of the working carb into the mis-calibrated one?
Drills can be purchased at McMaster-Carr. Include the metric sizes as well. Download the equivalent sheets from them also. Easy to do. Ask a local dyno guy if you can run those carbs over his dyno mule. If not rent the track. The above is oodles cheaper than beating around the bush with the mis-calibrated carb.

I disagree Bruce. The OP has a history of carb issues that he has tried to tune with carbs built by multiple builders not just TMC or Get’m which this thread is about.

If it were that easy and simple, we all could be carb builders! I'd bet drills at the racetrack messed up way more carbs than they fixed.
With any new race part, the end user also holds responsibility for the end results, it's not all on the vendor. I can't count how many times someone changed a part and all of a sudden the car runs like crap - so they adjust this and that with no results and blame the new part,, then they take it off and replace it with the old one and the issue still exists! Trailer gremlins are a real PIA! When the issues are above the end users pay grade, you get garbage in therefore garbage out. Not knocking anyone here, this is just the facts! Business producing any race parts have to deal with this on a regular basis, more so these days thanks to the internet.

So very true. Many people mess up a good carb because the think they know what they are doing. There is one carb company that has been in business for probably 30 years and still does not know what they are doing.

Can you say that louder? LOL So many times this is the case. I'm not calling out the OP. I just see this over and over.
On another note, I also see so many people change something and then blame anything else on the car for the problem.
THE PROBLEM JUST STARTED WITH THE CHANGE!!!! HELLO!!!

I could be wrong, but I don't see anything from the OP that indicates this is a TMC or Get'm carb. Did I miss something?

you're not aware of his previous posts here and elsewhere.
To recap, per his comments...
the TMC twin blade was a mess, Tony took it back and built him a dominator. Now the Get'm dominator is a mess.

I have totally lost trust in the original build on this I believe this may be set up for Q16 and we run C14 it has miss match main jets when I went to check them so what else is not correct time will tell.

With some of the carb issues the o.p. has had, im starting to wonder if he doesnt have an intake gasket leaking

Sharp Carb Builders will tell you that a really good Valve Job (where the Valves Seal really well) make the Carb shine, valve seal makes a difference.....so does having any intake tract leak as was suggested....Issue may not be the Carbs...

we have sprayed around the intake gasket and base plate gaskets with no change. if the gasket was leaking internally I would think I would see a change on my pan vac gauge and have oil on the plugs? motor is fresh from the engine shop and I suppose anything is possible the carb builder is working with the engine shop also since the motor has a rather large set of heads for the CID of the motor hopefully I will find out this weekend if we have it handled.

so, since Ed seems to know so much about everything what would you set up the calibration for the idle circuit in a non-oxygenated gas setup.

Maybe if you would post EVERYTHING about not only the carb but the engine/combo you'd get replies that are a little more than a guess but bottom-line is you chose to buy a Get'm carb through Sunset and now you're stuck with it. No one here is going to fix your latest carb issue with your latest carb builder except Get'm/Sunset!
AGAIN...
I've run carbs built by Holley, Pro Systems and ATM over the past 3+ decades, 4150s and Dominators on numerous BBC engines ranging in HP from 600 to 1300 and not one has ever had an issue out of the box getting from A to B under WOT. I don't understand why you always seem to have carb issues.
Chuck Nuytten, APD, TMC and Get'm to name just a few of the carb builders you have used, can't all have built you junk.
Contrary to what you think, your failures with carbs proves you can't lean how to set them up by asking on internet forums.This message has been edited. Last edited by: 1320racer,

This is why it`s important to dyno engines. I cant tell you how many bad carbs i tried right out of the box that were down 75-90 HP.

his numerous carb problems ain't due to lack of dyno time, his are due to the end user and him thinking he should be running quicker than he does.

Anytime I have sucked an intake gasket at the bottom, all I've gotten was an increase in idle and a little bit of smoke out of one header. If you are messing with your carb you might not notice a change in idle.

If* multiple carbs have been a problem and it’s not the end user… then you have a problem outside of the carb making you believe it’s a carb problem.
Have you placed the carb on someone else’s car with a similar motor?
Fuel pump bad? In line filter bad? I’ve had a mechanical pump cause a line to collapse when it was under high pressure making me chase all kinds of problems until I changed the line
