"Voicing" a rolled R

After weeks of practice I can finally get my tongue to vibrate, however it sounds more a "ch" machine gun like sound than a R.

Am I close? I don't know how to properly voice this noise for a Rolled R.

Also I can't seamlessly do it within a word. Like Carro. I'm saying "Ca "weird ch machine gun sound" on".

Am I making progress? Am I close? Any tips to get me to where I need to be? Thanks!
