Take your time.
I changed my mind on a bunch of stuff, ran into a bunch of issues, and when I got pissed off, I backed off. It'll always be there waiting for the next step.
I'm honestly not sure when mine will be fired up.
I have to yank the fuel tank and efi crap out, put in a fuel cell, lines and electric pump, then wire up some stuff still...
probably would have been running already had it not been such a shitty summer. Most of the time it's been too hot to do anything.
