How does the Auto decelerat?

[Bitsyncmaster]

Well I pulled the FD and as soon as I pulled the double return lines that pressure on the rest plate went away. The center piston is very free moving. When I pulled the PPR the larger O-ring (not the small sealing o-ring) was disintegrated and junk from it was in the piston side. I pulled the PPR piston and it and the small o-ring look good.

I don't know if that caused my problem but I'm thinking since I have the FD out on the bench, I will split it just make sure the inside is clean. That will let me blow out the screens on the injector hose side anyway. So I plan to use the old parts and just clean it up.

Well I split the FD. Looked clean inside so hoping the disintegrated O-ring was the cause of my problem. Have to get the hoses back connected but will probably be tomorrow to get that done.

Well I mess up something. Injectors are spraying all the time. I assume the center "piston" the turned down side points out. That side was dirty so I assumed that is the way it pointed.

You might check the roller bearing for the plunger, while you are in there...

By the way, that roller bearing is not spinning freely. Maybe that was causing the problem. Anyway, I pulled the FD apart and it looks like an O-split when I assembled it. I guess I need to put a little grease onto the o-rings so they can slide in.

[Bitsyncmaster]

My new O-rings are about .007" thinner than the old ones. Hope they work OK.

Roller bearing spins freely now. Just a little solvent on Q-tip cleaned it up. Added a little 3 in 1 oil also.

Got it back on the car and so far looking better. I get my 75 PSI primary pressure and it drops to 35 PSI when I shut off the pump.
Injectors are not spraying. I will need to do the base setting since I backed the adjustment way out.

I do have a very slight leak on one spot where the FD halfs meet but I will address that later.

Well no luck getting it fire. I adjusted the mixture just so one injector started to drip. Also that's the point you start hearing the screech from a few injectors. I would think I would get a pop anyway from the CSV but there has been nothing as far as any fire.

If you need injectors I'll have some available in 2 weeks or so.

Plugs fuel fouled??

Did you inspect the roller bearing for a flat spot? (Thinking about you saying it acts like it sticks and then jumps on the mixture earlier.)

I did not feel any flat spots when I was cleaning it. I check one plug and it is dry. I still think something is wrong with the FD. It holds rest pressure but when I press the air plate it does not cause any injection and the rest pressure stays.

I think my next step is to pull all injectors, put in jars and power up the fuel pump and press the air plate to see if they are working.
