Hi everybody,
I have a strange problem, can't put my finger on it, but can
certainly in it! Our Avanti was getting harder to start over time and
now I just can't get it to run.
After cranking a couple of times there is a sh*t load of gas in the
intake manifold, looks like a bath in there.
I've taken the carb (Carter AFB 3506S) apart replaced everything with a
rebuilt kit, set floats to levels as specified per manual. I connect a
suringe to the gas in line and filled the carb with gas and as expected
when the floats comes up, i get a some back pressure as the needles
close and can't add any more gas.
But back on the 289 it almost started, but alas, after cranking some
more I looked with a flash down the venturi and alas a bath of gas
again.
Before I put the car in the garage (a few months ago) it would stall
when idling, and if I got it running at a slightly higher rpm you could
see a shower of gas coming from the main jets. I know the V8 likes
gas, but this was abnormal, at least I hadn't seen such a "shower" of
gas go in there before.
I have no idea how so much gas can get "sucked" into the engine. I've
looked for cracks and gasket leaks, but i looks fine. It just seems
the engine is somehow creating a huge amount of vacuum... Right now
I'm thing about buying a new carburetor, but I'm not sure it will solve
the problem. When connecting a timing light I get flashes and all. As
some last resort measures, I've set the timing back to 0 degrees in
the hope it would start easier, and it does give a shot at, but
strangely only when cylinder one fires. But that might all be because
the other cylinders are soaked with gas now.
Any ideas anyone?
