A admission valve plate to suit the DLE 120 twin — a large two-stroke petrol engine for big scale models.
On this engine the component is the admission valve plate, which seats the reed petals against the crankcase.
Why this part matters: replaced if the seating face is scored or the plate is warped, either of which prevents the petals sealing.
Fitting note: Check the plate for flatness on a surface plate and fit a new gasket.
