I have me a new Rapid, butt it is missing the inertia weight and spring. There is some damage to the cocking dog an exhaust valve but these I can get from Dr Bob.
So part number 7c, 7d, and 7d are missing where can these be found.
Als think that the valve springs is not original as it looks new so think I need that also.
A should be able to make up an inertia weight, ideally hardened SS
The spring..easy enough to take measurments from one of your others and can probably find an online supplier with a similar spring off the shelf .
The valve and cap are the filter type, with filter OE spring length would be 16mm.
You'll probably need a seat to go in the cap to stop the spring from moving around.
Just contacted Dr Bob for the missing parts and some spares, it schould working again soon.
It will need a new exhaust valve, exhaust valve spring and hammer spring.
It has an origineel Theoben quick fill I am told.
