Re: Dizzy direction

Hi David,
When you turn it so that the front face of the vacuum canister (where 
the vacuum line attaches) runs directly into something, that's advancing 
it. When you turn it and the side or back of the canister hits 
something, that's retarding the timing. Viewed from the top, advance is 
clockwise.

Best regards,
Theo
