I would suggest going to the tip and looking for one. Only problem is most already have a tooth or 2 missing. I hate to accept it as well sometimes, but others I just put up with it
Was trying to fix a hot air damper on the Camira last week, snapped the flap off. That should mean new air filter assembly, but a slim chance of ever finding one. So I will have to use a glue to put it back on and hope it doesn't drop and melt on the exhaust manifold. Putting in a new (read expensive) choke pull off valve tomorrow and if I stuff this up there's going to be a problem haha.
Have sliced fingers, lost marbles and once almost sacrificed toes in the pursuit of perfection - often can't be stuffed especially when it often comes back to bite me or ends up no better
