I usually am pretty careful when disassembling and layout all components in sequence BUT I will check that too !
Thank you for your help aussietrev !
Cheers,
Gtrman.
PS: The model number on my mower is KU 398 A1 which I believe is a 1982-83 Silver Streak version with a flat Black plastic cover over the engine and not the more rounded cover as per this YouTube Video ?? Any clarification on model vintage is also appreciated.
