Subject: Ki-Gas Inlet Manifold Units
Hi Everyone.
I am in desperate need of some HELP.
My 1929 2 litre high chassis has developed a fault where it won't start in cold weather. It is fitted with the original Zenith carb which I have stripped/re-assembled and can find no fault. I have previously stripped and checked the Ki-gas pump using articles from Lag mags and info obtained from this site. The pump certainly forces fuel out when set-up on a test rig.
Whilst I have owned my car for many years and have rebuilt the engine I have never had the inlet manifold off or taken the pieces which screw into the inlet manifold apart as I could not get the small chrome plated brass nuts on the input pipe and the link pipe to undo. The manifold has 2 pipe connections.
I would like to establish exactly what the pieces that are threaded into the manifold consist of. I have always assumed there is some form of small jet and when fuel is forced through, it forms a type of spray. Is this correct?
If not how does it work and what do the components consist of.
I have looked through several motoring books but not been able to find anything about the manifold end only the actual pump operation.
I intend to strip the inlet manifold in the near future but though some might be able to give me some guidance!
Many Thanks
Mike
