Glad you got it working man! Still weird I don’t see a throttle trim. Not really familiar with modern traxxas radios. Good luck with break in and ask any questions you have along the way. Oddly enough, breaking in engines is one of the most satisfying parts of the RC hobby for me.
Your idle gap is way too big in the carb. As stated above make sure your throttle trim is set correctly, most likely your problem as your factory needle settings should be set rich, but always good to double check. Try and get that idle gap to close via your throttle trim in your radio.
