Yes, jetting can cause a hard start problem, or idle, or mid throttle, or full throttle as your 230 main suggests
pilot/airscrew controls start, idle and up to 1/4 throttle
the needle length, taper and clip settings controls 1/4 - 3/4 throttle
main jet controls 3/4 to full throttle
so for a hard start issue, look into the pilot (stock 32.5 has worked for every blaster I've tuned) and the airscrew setting
Tune the airscrew to achieve highest idle as described here, should be between 1/2 and 2-1/2 turns out ....
