thinking about the new msd atomic efi system
The funny thing is......the main complaint here is a driveability issue, caused by no choke, AND a fear of reliability. A new carb that is jetted for this combo would come in under $600, I would think. And I don't think there's really a justified fear of reliability with a brand new carb.
