2003 Sportster Le. Won’t stay running

[Kk0271]

Replaced new MPEM and many other parts finally got the boat back together it fires up with full choke but will not stay idling. Runs a few seconds and stalls again. If I flutter the choke i can keep it running for a bit but it shutters and stalls out again. Any help would be appreciated..

Is your idle set too low?

compression test ??

or has your accelerator pump fitting broken such as mine did the other day? Was tough to keep it running
