I Having A bad vacuum advance line day

Afternoon all.I'm trying to get the vacuum advance line installed in my post 60000 3A. The one that came off had a male fitting on the carb end and a female fitting on the distributor end. I get the male end threaded into the carb body only about 3/4 of the way and it stops not to budge any further. That wouldn't bother me except for the fact that the line is still loose. Don't figure that's a good sign. I looked at it with a mirror but could see nothing wrong. The carb bodies went to Joe Curto for new shafts and I rebuilt them from that point. To be honest I never looked at that part of the front carb. Didn't even give it a thought. I do know that the line is clear and the carb body is clear.
So my question is what's wrong? Bad fitting? Bad threads in the carb body? Wrong application? Wrong Line? Time to take the carbs off for a proper inspection?


Your thoughts very much appreciated.

Those carb bodies are aluminium, so I would suggest taking off the front carb where it will be easier to assess what is happening with the tube and fitting. You don't want to be cross threading or messing up anything on the carb body.

Some things to look for...
Messed up threads in carb body
Threaded fitting not rotating freely around the tube
Possible cross-threading...easier to evaluate with carb off.
Fitting itself with bad threads

Maybe some pics when you get the carb off might help us see what the problem might be.

Edit: BTW Dick, I enjoyed looking at those "Pencil" pictures. :smile:
 
I am just guessing here; could it be that your carb body wants the adapter instead of the male line fitting? I was under the impression that the adaptor (Stanpart 108364) persisted through the end of SU H6 usage (during the TR4 run). That seems to be supported by the TRF database entry for SUAUC4490 (which is the number they use for it).

But I haven't worked on many post-60K cars, so I could be off-base here.
 
Well I pulled the carbs off and what I was trying to do and not good for my carb. I think its all right. Randall I have been talking to Dave at TRF about the adaptor and they have one and soon I will have it. The fun thing is finding a line with two female fittings.
Sheesh this stuff gets complicated.

Aloha Dick,

I made my own line using 1/8 compression olives and nuts from ACE Hardware. I got 1/8 copper tubing from an appliance repair parts store, 1/8" OD capillary tubing that is commonly used in refrigeration.
 
:iagree:
Except I still had the old nuts, so I wasn't sure if they were the same.
