Will ether one of these be a better replacement for the traxxas carb on a 3.3 I got them both off eBay for 6 bucks.

1. OS 20E came off a NOS rg.21 never ran
2. RB nova mega, novarossi carb. Came from a nova mega JP black buggy motor which had about 8 tanks before we were sponsored and switch to OS.
