1972 Duster Build with my Daughter
Here are the FBO parts for setting the timing advance.
After setting the gap in the pickup to 0.008" we spun it while connected to the oscilloscope. Here is what the signal looks like. The sharp edge is when the sharp edge of the cam passes by the pick up pole.
So it turns out the hole I drilled for the aftermarket booster was needed to get the '73 booster in the '72. I installed a body plug in the old hole.
Now the NOS master cylinder. I disassembled it the other night and used my brake cylinder hone to clean up the bore.
First thing is the installed the flare bushing. Here is how I get them off. This an old tool for removing the emission plugs to get to idle screws on carbs. Remember those? Screw in and use the slide hammer to pull it out. Easy.
In this cylinder only the front tank has a check valve behind the flair bushing. The Coronet had one behind both. The kit was correct and only gave me one so make sure you note it when your pull it apart..
Just set them down in the housing.
I use the lines to thread in and push the flare bushing into the housing. You can feel them go in and bottom out..
Now lub up the bore and new pistons
Front one goes in first. Be careful to not cut them so go easy and twist slightly.
