74 power wagon dream truck...

Yes I got it runnin ...Okay. I pulled the manifold and re-did it. No more leaks up top. Just have to do the rear main seal.

there is a slight hesitation/stumble off idle that I have to work out. Also happens when I’m driving and I want to punch it, there’s a stumble, I have to ease into it.

it’s still open header, I’m sure it’s having a lean condition because of that, when I get exhaust made and installed do you think that might clear it up?

I played around with a bigger pump shot, then moving the lever to the other hole for less, not much change. I tuned to the most vacuum, that helped some. I gotta get that stumble worked out.

Maybe. I wouldn't try to tune on it till then though.
