POSSIBLY, if im honest its been a good 2 years since i had all the dramas with my car and i cant remember now how you set the mixture, and i dont intend on using MFI ever again.
If its set too weka then yes you will have a starting problem on your hands!
See if you can get it started by pushing the flap gently a couple of mm while its being cranked over.
If it starts this is your problem
