Centrifugal clutch or torque converter, what are you using?

I don't know what brand trike I have, it's a 24" but I bought a Bilt Hard 212cc 7hp motor off of Amazon, I started with a centrifugal clutch and read somewhere the reason it burned up on the first trip was due to my wheel size, I first used a hub adapter but it broke and tore up my spokes at 2miles of use on the clutch, with a little grinding and a fork swap I was able to use a 26" mag wheel I had as a front tire and made a 8 mile trip to work but that evening I had the motor die several times because I didn't take out the oil sensor, the motor actually never made it to a high enough rpm and actually smoked my clutch so I got a torque converter and tomorrow will be trip #1.

My question is what are y'all running with, centrifugal clutch or a torque converter?
 
I had a tachometer connected but it read 1900 rpm the whole ride, my rear sprocket is 36 teeth I believe, this is how I first had it set up with the centrifugal clutch and the hub adapter broke less than 2 miles in

It read 1900 because your gear ratio is way too tall and your clutch was slipping. Your clutch would probably lock up at 50mph. You want it to lock around 20mph so you will need another reduction. A torque converter isn’t going to help much if you’re too tall, you really need another reduction or go to very small rears like 16” or so.
 
I know pictures can be deceiving. Your does Not look like it is sitting Straight? That will rip your sprocket out real quick.
