pz26

Sup guys, I've been lurking here for over a year and learned a lot, but i need a little advice. I've just fitted a pz26 carb to my motor and it runs like a raped ape on full choke. opening the choke at all and it dies. i didn't have time to check for an air leak do to the massive rains here...

Which manifold will connect the pz26 to the gx200 head? I'm thinking its just the regular one like the Mikuni. Also, is anyone using the ebay pz26? thanks SJ
