64 dart convert to EFI

I don’t know what caused the sputtering, they took the carb back out and identified a rod/lever (?) out of place/alignment. I don’t have my note w me at the moment.
Noted on the units being universal and to just select the correct size. Noted on the Walbro, will look into it.
Just spent a couple hours on YouTube watching Sniper install videos. Actually feels approachable if I can get the space.
I’m going to follow up w mechanic asking them to order and install a sniper, or to ID the current carb issue and I’ll consider EFI swap at a later date.
Again I appreciate the questions, advice, and suggestions all
