If you seem to only be having problem to the Last 3 cyl. Have you thought about also rechecking Valve lash??? A carb in it self would not show Problems to only 3 chambers No matter what way it sat on the intake. If it is in the Last two I would say Yes a Intake issue But with it seemingly to be ??sounding?? as the Last 3 chambers ?? Problem I see with that Is it would also have to effect the 3&4 Now 4 ,5 6 Because if 4 had a Intake issue So should Number 3 Knowning That 3&4 are on the same runner. I would say Pull each Plug wire to see if the Motor changes any. One Other trick You can do Which Hurts Nothing Is to Take a squirt Bottle to all the Header tubes and see How the water evaporates off Each tube This will help pin point a chamber/cyl. issue??
