The Insulator makes it too large and it will not go into the crank case. As a comparison, it should just drop in like it does with the OS Crankcase.
Guess i just did $70usd as i don't have a Novarossi carb i can use on it

OS crab is not fit since the carb neck diameter is 13mm.
Hyper 12 is same as Novarossi...... 12mm.
