i have adjusted the ballance wheel fully but the clock is still going about 5 minutes slow per day. What do i do.

the next part becomes special you have to remove the studs in the balance wheel in a particular order always diagonally opposite each other you may find how to do this if you do a internet search.
The balance wheel has to be removed and supported to knock the studs out once out they will not refit hence maybe better to entrust to a clock repairer.
