1.7 with dual webers. I am experience some weirdness on startup. Hot or cold I am able to fire up the car and it idles up. But after a minute or so it starts stumbling and dies out. Really hard to keep it running.
Then I can't fire it up again without letting it sit a few minutes and trying again. After it gets going I can drive it piss out of it all day long but...as soon as I turn it off and it sits more than 5 minutes; issue surfaces.

I have a Carter fuel pump installed up front and pushing 3psi. I did some idle mixture adjustments a little while ago and realized car was a bit rich. Not sure if that's correlated.

Fuel filter?
Idle jets cleaned?

Clean on both. This isn't a continuous issue. Only happens a minute or two after starting up.
