Help!
I recently began a rear brake job on my 76 TR6 due to a leaking master
cylinder. While I had the rear jacked up to remove the old components and
clean the backing plate I noticed a distinct gasoline smell. I looked at the
front and saw gasoline dropping underneath the car. Upon opening the hood, I
saw fuel leaking from my foremost carburetor. I thought that perhaps my float
had stuck because of the angle of the car so I jacked the front up to the same
level. The car has been on jack stands for about a week. I have gotten an
occasional gasoline smell in my garage and thought that it was some of the
residual gasoline from the original leak because I did not see any further
evidence of gasoline dripping under the carburetor. However, today I felt
under the carburetor and it was wet with gas. I think now that the gas
continued to leak, but was evaporating before it could drip. I am very
concerned with this situation because my garage is in my basement and
contiguous with the rest of my house. I need to find the way to stop this
leak for a number of safety reasons.
I have 175 CD-2 carburetors on my car. There is a small circular yellow
plastic cap on the bottom of the carburetor around which the fuel is leaking.
The fuel is leaking at a much higher rate since I manipulated the cap. The
cap turns freely and will not unscrew or screw down tighter. I have a Haynes
manual on carburetors but it only shows that the jet is located there. The
arrangement I see under my carbs is not depicted in the manual. The other
carburetor has an identical arrangement but the cap feels tight to the fuel
chamber. I have clamped off the fuel line going to the carburetor, but I am
concerned that there is enough fuel remaining in the float chamber to continue
to leak for some time. I would like to know if I can simply remove the float
chamber with the carburetor in position and deal with the problem or if there
is a simple way to remove the plastic cap. Any assistance would be greatly
appreciated.
