One of these huh:
Notice the part on the accelerator pump at the top of this page.
Does this look familiar? I found it with a bunch of other YF drawings. This is more of a mechanical schematic than the actual layout.
The old YF and New YF are so close, some of the same gaskets are similarly shaped after 30 years.
Actually there is a great writeup at the CJ3BSite.com site.
Here is another site with some info.
Still you should get a strong flow of gas coming out of the port for the accelerator pump. Make sure all your gaskets were installed correctly, you could inadvertently block off a hole, and all passages are clear.
