If you want a nicer carb maybe consider the dax carb:
It is called rt carb high performance
It has a semi auto choke (hehe kinda confusing)
What you do is you lock it down and start the engine. When the engine is warmed up you just twist the throttle all the way and it clicks open.
The carb itself is somewhere around $30 dollars and I think you need to buy the cable also, another 10 dollars.
I run the carb myself and love it.
