After rebuild done 50 miles but now won’t tick over without choke on. Complete engine rebuild new carb must say left it 6 weeks without touching it if that helps. Would jets become blocked

Possibly blocked ? It Won’t hurt to blow it all through with compressed air
How clean is the petrol tank/petrol tap?

Pilot jet is blocked, clean the whole carb, the pilot jet is the small one numbered 45 to 50 or very close. 10 minute job.
