Models: All engines
Nearly all Robin engines require a restrictor in the intake when fitted with a Donaldson Air Cleaner (excludes Diesels DY23/27, DY41/42, Petrol EH65 engine series). Please be aware that nearly all Crommelins manufactured products have restrictors fitted to the Precleaner or the Rain Cap and that if the restrictor is removed or lost there are possibilities that a Robin engine may suffer severe surging under load, higher revs and the engine may run hot.
