Does anybody know if there exists a tool for adjusting the spring perches on the late '70's distributors? The perches can be reached from above when removing the cap, and that may come in handy when fine-tuning the advance curve. I have thought about modifying a screwdriver, but if the tool exists, please tell me where to get it.
An alternative would be to open the vent hole in the floor of the dizzy's body, and make it big enough for a small socket to reach the nuts on the underside. It can then be closed with a rubber grommet when not in use.
Does anybody know approximately how much a secondary spring's action can be delayed by adjusting the spring perches?
My camera's autofocus cannot be oversteered, so I had some difficulties getting clear pictures, sorry about that. There are details here not seen by those with older distributors, so I took some pics!
Here you can clearly see the black ring of old lube, that indicate the amount of adjustment from one revolution of the perch. The flat spot on the perch indicate the direction of max offline. In the little picture you can also see that the centerline of the perch is clearly not in line with the nut.
I also have a problem with the drawing vs. my distributor. In the drawing, taken from the '78 manual, there is a seal on the axle, pictured below 'shaft assembly'. There was no seal or washer on my axle. In the photo of the axle, you can clearly see that the diameter of the axle is smaller, just under the plate for the advance mechanism, and the area is quite course compared to the rest of the axle. Is the seal abandoned on the later distributors? A murky photo of the housing, but you can see the channels from the underside of the dizzy housing entering the area between the lower and upper bushings for the axle. I assume that the channels are thought for axle bushing lubrication by oil mist/splash, so on a worn axle a seal may have a function, not letting oil mist into the dizzy housing.
Comments anyone?
In the distributor drawing, there is a gasket, retainer and washer between the house and the gear, on my dizzy there was only a washer. What is correct?
