DK4A WEAR OR NOT ?

[Peter Clayton]

Thanks for the replies gentlemen, After  stripping  the gear and removing the spindle, I  welded the worn areas and filed  the holes back to 8.5 mm  diameter. Now reassembled the engine is running smoothly but as there was some free play in the bob weights and the springs slightly stretched , I'll run it as is at present but will be looking at getting a 009 unit and possibly electronic operation to help smooth out any roughness in operation.
