This morning, took off the air clean box, adjusted the
Ratco cable linkage so the gas pedal was 1/2" below the
brake perdal. Put everything back together.

Nice 2 hour drive running errands;, engine purring at
900 rpms at stop lights or stop and go traffic. Pulled
off the road onto the shoulder to gab with a forum member
for maybe 10 minutes. 900 rpms, temp 180.

Suddenly engine idle falls to 400 rpms and quits. I turn
off key. Gab a few more minutes. With difficulty the engine
started but would not hold an idle. Made it home with difficulty.

In my garage, standing beside carbs, holding carbs open for
1200 rpms, I hear a faint hissing sound that was not there
this morning.

I checked all the obvious culprits in the electrical as
well as the vacuum lines. I found nothing obviously fallen
off or broken. When I shut the key off, a faint hissing
sound continued very briefly after engine quit. It "seems"
to be located toward the center/top on the carb side of the
engine.

Any suggestions on this one? Normal fuel supply thru the glass filter case.

thanks,

Dale
 
Sounds like your intake vacuum that feeds your brake servo came aloose. Sometimes the large nut that secures that vacuum line will need to be tightened. Even the extra vacuum inlet that should be capped off with a rubber plug will fall off. Assuming you removed the pollution line from it.
 
Your problem is a classic description of a vacuum leak. It;s there, probably a cracked rubber line or the leaking behind the banjo bolt or fitting on the manifold.
 
Don't have a banjo fitting. I could have loosened the brake hose as bill suggests. Odd, it happened after 2 hours of perfect driving.

I also thought vacuum leak immediately.

I'll check after dinner. Balsamic vinegar porkchops!!

If the vacuum leak doesn't fix it, check to see if your points closed up. It will run, but won't idle and power will be down.

Youz guys BOTH win a Big Cee-gar!!

1/2" long split end of the brake servo hose right at the
intake manifold nipple. I sliced off the split end,
reinstalled the hose and Amos back to purring at 900 rpms.

Whew! I was worried it might be a blown head gasket or
YEEGADS! thrust washers blowing up the engine.

The bain power on this forum is astounding!

thnaks,

You need to eat pork chops more often.

Good diagnosis job.
 
Tinster
these things happen with old cars. Last week whilst driving to work the vacuum activated diaphragm in my fuel metering unit split. An easy replacement but just one of those ongoing maintenance things..........

Hey Craig!

Yeah, even ten thumbs, non-mechanic Dale kinda figured this
was a simple issue. I would probably have found it myself
in daylight when I could see where the hiss was originating.

Nice beach photo you posted awhile back.

Thank goodness you fixed it. I had a sinking feeling I might have inadvertently been the cause of the problem by enticing you to fiddle with your gas pedal height!
 
Nope, not to worry Julian!

But you did give me the idea to try and lower my gas pedal.
As installed, my right foot was not touching the floor when
I pushed the pedal to shift. It was suspended above the
pedal.

I now have the pedal lowered to 1/2' below the brake pedal
level and my right foot heel rests on the floor. But I now
only get maybe 70-80% carb opening. I max out at 3,300 rpms
in 3rd gear with the pedal on the floor.

Paul gave me tip on how I might get more carb opening and
keep the gas pedal in a decent position.

regards,

dale
 
Update in daylight:

The repaired brake servo hose works like a charm.
Car started right up, nice warm idle and I drove the Six
a solid hour in heavy rush hour traffic to pick up the Mrs.
housekeeper.

Now, since I carry a portable Sears tool department in my
trunk, I'm taking Amos down to the boatyard to complete my
trailer suspension rebuild on one side.

see ya later,

Given your previous adventures in putting this car on the road, I think especially you are allowed to have break from cumbersome repairs and have none or just relatively simple fix-in-a-minute type of troubles for a while.

Actually, that faint hissing sound, if you got up real close, was a giant sucking sound of money leaving your wallet.....

In Dale's case, I think the faint hissing from his wallet was more like a Category 3 hurricane. /bcforum/images/%%GRAEMLIN_URL%%/lol.gif

Oh No!! Wendy just informed THE Donald HAS NOT been pumping $$ into my black hole TR6 project. It's been coming out of my personal stash. Wendy informs I am now broke.
I need me a TR6 stimulus package to pay off my debts!!

No offense, Boss! Just kidding. /bcforum/images/%%GRAEMLIN_URL%%/devilgrin.gif
