Carb question

[73CBnoob]

So I bought a 73 cb450 and didn't realize that it has a 500t engine in it but its still running 450 carbs... Does anyone know if these carbs will work for this engine or do I need to buy the 500t carbs... Also I know that the 500 carbs have the same size slow jets in them but have 145 main jets instead of 133 main jets. So I switched these jets out and now it's running rich. So should I stick with the smaller 133 main jets or even go smaller because the air is thinner here in Colorado. Anyones help would be much appreciated.

Thanks

The 500t is basically just a bored out 450. Main differences are the 'styling' (pie warmer on exhaust, etc)
I would put the 133 back in and do some testing. You may need to go slightly smaller but as carbs are pre-EPA they probably work better than the 500T carbs
