Monoblock For C15?

I'm putting together a simple C15 for trials. The existing carb is a monoblock 376/ 258 and under the dirt/ cobwebs appears serviceable. I believe but am not sure that it has a 1 1/16" choke. Should this be adequate for trials? If it makes a difference, the engine has the standard cam and 40-441 head. (big valve - 11/16" choke per the RR book)

The other option at hand is a 22mm TLR200 carb but the mounting is different.
