It's fairy simple: as long as it's tight after throttle, idle goes down.

So you have a leak either across the throttle or after the throttle. Cracked phenolic intake stacks are common, as are leaky intake/head gaskets. Big brass throttle bypass valve can be removed and hoses plugged.

Pressurize whole system with shop air and check for leaks. Use max 1.0 bar.
