Shipswrong Disease.
My distributor is original to the car (it seems, anyway). It's a DM2, and the
points that I've been able to get didn't fit right. Also, the top and bottom
points plates were wildly loose in the center and wobbled badly. So I sourced
an upper/lower points plate for a 25D.
Things started going squishy.
For starters, the new lower plate did not have the pronged mounts for the
terminal bush (where the coil wire attaches). So to make things fit, I took the
old bottom plate off my DM2 dizzy, attached it to the new 25D top plate, and
was in business.
When I took the plates off the dizzy, I inspected the centrifugal weights. I
should have known better. If I hadn't seen the problem, it wouldn't have
existed, right? One of the weights had the spring completely broken and off.
Off I went to the hardware store, picked up some small light action springs,
and manufactured replacements that let the weights swing easily, yet rebound.
At the same time, I cleaned and put tiny drops of oil on the action pins.
So two questions:
After reassembly, I seem to lack power, and hear pinging I didn't hear before
on acceleration. I seem to have two courses of action that may be correct. 1)
Do I simply advance the timing, thinking that the new top plate from the 25D is
more retarded than the DM2? ...Or 2) Do I need to order the $30 set of springs
because the ones I manufactured don't have the right physical properties?
