OS 55 AX. New In Box (CODE 473)

This engine is brand new and it has never been turned over. OS tolerances are very tight and a new ABN engine will not turn over and will get stuck if you try to turn it over unless it is first heated up prior and part of the running in process.
If it is forced and run otherwise the engine will have less compression, poor idle ability, lower performance and a shorter lifespan.
Complete in the box with tool set and OS8 Glowpug.
