Before going for touchweight issues, make sure piano is well-regulated.
Things I'd look at before touchweight would be:
1. Tight hammer flanges.
2. Tight whippen flanges.
3. Tight balance rail key holes. Key's should drop on the pins easily.
4. Tight front rail key bushings. Lift key; it should drop easily.
5. Dampers lifting too early. Check that dampers don't lift from key before hammer is 1/2 to strings; put finger on damper head to feel for lift.
6. Hammer knuckles badly worn. If they're flattened this is major friction.
7. Jack alignment, repetition lever height, letoff, etc.: basic regulation.
8. Drop is excessive.
That's a start. I always go for lubrication/friction and regulation first and work from there; this solves 99% of problems with 'heavy' pianos.

Greetings,
That really isn't enough info for any of us to offer suggestions. Yes, if the leads were removed from the keys, the touch will be heavier, but it may have been too light with them in there and new action parts installed.
Suggestions will be more pertinent if we know some of the down/up weights, Front weights, and Strike weights, as well as what sort of action ratio you have going. Friction can play a part, but with. "rebuilt" action, there is a lot of room for mismatched parts.
Regards,

Working for a customer with a 1927 Mason & Hamlin grand. "Recently" rebuilt. Maybe a decade or so. Used little since then. Customer complains of heavy touch. I plan to iron the key bushings and clean and lubricate the key pins. I noticed that many of the round key leads have either been removed or fallen out at some point. Most of the white keys are missing at least one. I've purchased a set of leads, but have no experience with "re-weighting" keys so-to-speak.
Assuming that the bushing and key pin work doesn't yield the results he wants, how should I approach the issue of the missing key weights?
