Gasket won't come off!!!!

I did some work on my car's carburetor (Accord '87 LX) and now it's time to
put it back on. But the gasket between the intake manifold and the EFE
heater won't come off... It just won't. No way.

That gasket says it's been there since 1987 and there's no power on this
earth that's going to take it off...

I went out and bought some gasket remover, sprayed it on, waited, scrubbed
it, etc, etc, but no. The gasket laughed right at my face. In the
process, I have even made a few minor scratches and I'm afraid that
continuing may create even more scratches and damage the surface to the
point that the seal will be compromised, no matter how much torque I apply
when installing the carburetor.

How can I take what's left of the gasket off?

Hi,
Tried WD40 spray? It is actually solvent. Soak it with WD40 and try.

I find that a single sided razor blade did the trick with my water pump on
another make of car, (with a lot of work). Make sure it's a new blade. I
would try this in conjuction with the WD40 idea. Plan on 30-40 minutes of
hard labor. Be careful not to scratch up the metal of the carburetor.
Otherwise use a light grade of sandpaper to smooth out any MINOR nicks in
the metal that you may add.
 
WD40 plus a single sided razor did the trick. I still sanded the surface
the best I could and cleaned it with a rag. Placed a new gasket, the EFE
heater, a new o-ring and then the carburetor.

Now the engine starts but dies immediately. I checked the accelerator pump
and it appears to be working; pressing the accelerator causes a stream of
gasoline to enter the carburetor. You can see gasoline through the float
level inspection window. The accelerator pump diaphram was one of the parts
that I replaced when I bought a new carburetor kit. I suspect a small
gasoline leak at the pump because the area seemed a little "wet" after I
turned off the engine.

I suspect a vacuum leak right at the gasket. I torqued the carburetor
mounting nuts to 15ft/lbs. I've heard that sometimes the EFE heaters can
warp causing leaks... that or I really messed up the intake manifold
surface. Can I use hi-temperature gasket sealant?

Thanks for your replies.

Hi,
Even if you pump the pedal, engine dies? Is fuel pump known to work OK?
Finer than sand paper is emery stone.
There is gasket sealant(or so called gaksket maker) you can use.
if you think there is vacuum leak, spray WD40 genrerously around the
suspect spot. RPM will pick up when you hit it right.
Just minute, you said engine keeps dying, then this test is no good yet.

If you pump the pedal the engine keeps running. It start at about 3000 rpm,
then within a second it engine rpm goes straight down and engine dies. You
need to keep pumping the pedal when you see engine rpm starting to go down.
I can maintain the engine running like this, but as soon as I take my foot
of the pedal the engine dies.

Just checking, but I have to ask, if I remember correctly there is usually a
vacuum line that you need to plug (at least one but there may be two) if you
are trying to run the car without the air cleaner. Are you sure that you
have this plugged? Also, have you left any other hoses off that might be
causing a huge vacuum leak?

There are 4 vacuum lines that connect to the air filter assembly; I plugged
all of them. I have replaced most vacuum lines, but they seem to be a
little "loose", they don't seem to fit tight. I'm looking into that and
will probably clamp down all connections.

If you used SAE sized vacuum line, then this could explain why they're
loose. I believe that Honda uses metric sized tubing. Metric sized vacuum
line is a little harder to find but should be readily available.
