My 1835cc CMC has a Brazilian 050 distributor with the rotor set 90* left of where the common #1 plug wire would normally be (4 o'clock) Its seems it is set at 7 o'clock. Being that this was to the best of my knowledge a running fine tuned machine prior to it going to sleep in the early 90's --15,000 miles on the clock. What I have read is there are dizzy's that use a 90* offset to the normal position. The pic shows that the hammered dent (TDC) is at the case split and plug wires were routed to fire from the 7 o'clock position.

 I noticed that the new points I put in had a bluing on them 5 minutes after running the car. So instead of ordering a new coil, points, rotor etc I made a decision. The car has not yet hit the road--getting down to the last few items.

Being that I wanted to upgrade the dizzy and rid myself of adjusting points I opted for a Magna Spark Kit. 

Wondering if I just install the new dizzy right out of the box with the installed blue spring setup?

What are some do's and don'ts?

The Magnaspark kit SHOULD have come with the light silver+light silver springs installed. The springs and bushings affect the rate of advance and dictate when the distributor reaches max advance. With the heaviest springs installed it won't reach max advance until 5500 rpm and if you install the weakest springs and bushings the car will reach max advance at 2500 rpm. If yours came with the blue springs installed you'll have to change them.

Here's the install sheet if you didn't get it:

Set it up so the rotor is on the #1 plug wire at TDC, start it and turn to adjust. If it won't start, turn it and try to start it until it does start. These electronic ignitions can be a little misleading to set up. Get her idling. Turn the disty until the idle is best. 

Everyone here like to use a timing light and set it to about 28-32 degrees at 3000, which should be max advance (see above post). Set it at 30, warm it up, drive it, find a nice hill and lug it up the hill in 3rd gear. Listen for that rattle can sound that says "ping" detonation/preignition. If you hear it, back off the throttle, downshift, head home and reduce the timing to 28. If you don't hear it, try 32 degrees if you want. 

You really don't have to spring for the degree pulley..It's easy to do , bring the motor up to TDC with #1 pointing the the mark in the dizzy,  then mark 90 degrees on the pulley ( @ 3 O'Clock)  divide that by 2 = 45, divide again by 2= 22.5 then you can figure your 30 degree BTDC max and mark that. Or, buy a $3.00 plastic protractor with degrees printed on it.

Sounds like the disti drive pinion got dropped in a tooth or two off and that's why your rotor lines up with the scribe mark around 7o'clock.  No big deal and the disti really doesn't care so you can just leave it there.

The alternative is to get a really strong shop magnet, slide it down the disti drive hole and try to get the pinion drive gear out (it has to rotate anti-clockwise about 90° as it's coming out).   Once it's out, "glue" it to the bottom of the distributor drive shaft with a small glob of automotive grease, rotate the rotor to about 2 o'clock and gently slide the whole shebang down into the drive hole to catch the gear on the camshaft.  If you're very lucky the drive gear will not separate from the pinion drive and will engage with the camshaft gear and slip into place, finally lining up with about 4 o'clock.  Sounds easy, but can be exasperating, trust me.  If it were my engine, I would live with #1 at 7 o'clock on the disti housing.
