Wider range adjustable Main Jet

I would like to see a wider range adjustable main jet that would allow
purging of particles big enough to clog the current fixed main jet orifice.
The adjustment would also be able to lean the mixture as much as the
current adjustable jet.

The nice feature of such a adjustable wide range jet is that particles
could be removed and. possibly. the fuel line could be bleed as well without
the necessity of shutting down the engine, waiting 30 minutes or longer
for it cool and removing the fixed passage jet. This would be a great
help in a risky passage where shutdown is not a good or safe option.

As I recall, main jet is about .043 whether or not you have the adjustable needle. With the adjustable needle, why not just open up the jet to .062 or so? Easily done with a 1/16 drill bit.
