I'm looking to setup my tubeless tires.
I was hoping that I could use my car compressor (schrader) for this but after I remove the inner core of the valve the schrader to presta adapter has nothing to thread on.
It uses the smaller thread on the inner core.
The only option is to use the inner core but this doesn't give me enough power to seat the tires in the rim beads.
Does this kind of adapter exist?
If I do a quick google all I see is the same adapter I have.

No valves have the connection you want.
Have you checked whether the tape is intact after trying to seat the tires? Sounds like a hole punctured in a tape or just tape pulled to the side by tire lever when you were fighting with the tire.
I pop out the core and usually manage to do it with my plain old track pump. If not I have just used a CO2 to seat it. I bought one of the little Chinese electric pumps. Ihaven’t had to seat a tire since I bought it, so I don’t know if it would work or not.
I do have some adapters that stick into the schrader side and you can just press it over the presta valve without threading. I believe I got them with some cores off Ali express a while ago.
Make your own, snip the valve stem out of a presta valve, and threadlock it into one of the presta adaptors.
Will be fine for seating tubeless.
That said, if you can’t seat your tubeless with a compressor through the valve, you need to look at your tyre/tape setup.
Are you positive it won’t thread onto the body? I have some cheap amazon ones and they certainly do.

These fit on the bodies without the core. Unless for some reason my valves are different than yours.
