forms of to-infinitive negative

We formulate questions expecting a "no" answer with a negative question and a positive reinforcer e..g. "You don't want to break the faucet, do you?". If you wished to ask a question expecting a "yes" answer, you could reverse this e.g "You want to not break the faucet, don't you?" However most native speakers would not ask the question in that way.

Original sentence is wrong, modified sentence is OK

It is stupid to bet on grammar.

Oh terrible flaw there... Sorry
The original sentence was " you don't want to break the faucet, do you?
modified sentence was "you want not to break the faucet, don't you?

I knew that tag questions were wrong.
Let's talk about this part.

#1 I want not to break the faucet
#2 I want to not break the faucet.

Question. are #1 and #2 grammatically okay???
I don't think so....

I know that any native eng users would find those sentences weird.
but I want to know a way to explain why.
I just told everyone that "I don't want to break the faucet" is correct negative form sentence.

When can we use 'not+to+V' or 'to+not+V' ?
and when we can't?

thanks for your attention. I really appreciate.
and that bet thing was just for a bottle of beer, don't worry. thanks

We use the negative form e.g. I don't want to burn the toast, when we are focussing on avoiding an undesirable outcome (something happening) (burning the toast in this case). Now consider these:

1. I want to speak to Mr Smith at the meeting.
2. I don't want to not speak to Mr Smith at the meeting.
3. I don't want not to speak to Mr Smith at the meeting.

1. expresses a desire for something to happen; 2 and 3 express a desire to avoid something happening (e.g. showing disrespect to Mr Smith).
