Hi - a new to me 1990 RRC came to me in pieces recently. In sussing out spark issues, it appears that the PO threw a bunch of parts at the problem, without diagnosis. I have read a number of threads here, but am seeing some conflicting information.
My first question relates to the mechanical advance on the distributor. This list of information provided by someone in the community references testing the mechanical advance by turning the rotor counter-clockwise to test the spring action. I am seeing that the rotor only turns clockwise, with counter-clockwise return action bringing it back to a home position. In taking apart the distributor it does not appear that it can be reassembled to allow for the reverse of this scenario. Is the reference to turning the rotor counter-clockwise incorrect?
Also, the tophat is completely missing on this distributor - how critical is that piece?
Thanks - and I appreciate this community being here for us newbies. I am part of other vehicle support groups (Landcruisers, VW Vanagons and vintage Triumphs) and it is so great to have the resources available.
