Check your using the right gasket between the metering block and the body.
one has an open area above the power valve that uses a small O ring gasket.
that that makes up the difference in the recess.
One has no open area with a small hole that seals to the body for a flush mount. This is the accelerator pump transfer hole.

Use the wrong one and your going to have problems/flooding at idle.
This is one problem with universal kit's to rebuild several different models, it's easy to get the wrong parts or gaskets put in. This is why they say in the inst. to compare closely with the part/gasket your removing. Failure to get the right gasket in there will suck fuel out of the accelerator pump reservoir into the area behind the power valve. That will eat up the diaphragm on the power valve over time. Now, with that vacuum area full of fuel, the vacuum port that feeds the signal to the power valve will be sucking fuel also causing an over rich idle condition.
