i tested it by blowing through my fuel line. went easy until there was a wee bit of gas in the slight glass then i felt resistance(float shutting off the flow).
this place either better fix it for free or they get an earful from me
and my motor is going to be carb only, as i have an '82 block/head with no provions for an EFI manifold like '83-up blocks. if i do it again i'll probably go with an '85 or newer block and a new engnbldr head as there's a lot less headaches than working with the early engines.
Do it, I like showing up the EFI guy's anyways. I have yet to have my carb lean out from near vert inclines or declines and it runs sideways past 30 degrees so as far as I can tell it just doesn't run upside down. I like more mechanical and less electrical anyways if there is a problem it's easier to fix.
