My 340 has a Barry Grant Speed Demon 650 with vac secondaries. The manual choke has been binding up and driving me kinda insane.

I was thinking of swapping a Holley manual choke kit onto it, it looks like a better design and it's all metal as opposed to the plastic bits on the BG choke. Is this a straight swap? Any gotchas? I read somewhere else there are no instructions with the Holley kit.
