How do I clean my 2.0 dizzy? Options

[Cevan]

While it rains for the next 36-48 hours, I figured I would eliminate some of the potential causes of my high idle ('74 2.0 D-jet motor). I had read that advance plates don't move freely could cause issues so I pulled the dizzy and proceeded to try and clean it.

I removed the two screws that hold the trigger points in place. I tried to pull them out but they only come out so far. I don't want to yank them out if something inside is holding them in.

Also, I'm not sure how to proceed in cleaning the advance plates. It looks like I need to remove the small circlip that holds the arm that extends from the vacuum advance. Then there is the wire that appears to be soldered between two pieces. Can the dizzy be cleaned and lubed without disassembling all of this or can I test the advance plates to see if they move freely.

I did hook up a vacuum gauge to the vacuum advance port and the arm did move slightly when I introduced some vacuum.

Here is a picture. Btw, the dizzy is a 039 905 205A, which I believe is correct for the '74 2.0 motor.

LOL...I was on the phone with Rick(918) when you called.
I figured I would call you back...to funny, you got it all done while we talked....and talked...

Suck on the vacuum cansiter, see if it (a) holds a vacuum...its a potential leak...and B moves the plates correctly...you have to spin the unit by hand while you put a vacuum on the canister to overcome the mechanical issues...but it should spin the top plate...bottom one stays put.
