Hi there,
Here a message from the Netherlands.
A friend of mine owns a Pontiac 1930 Six. He bougth it out of a crate en assembled it again. So far, so good.
The engine is equiped with a Marvel Carbureter
. The fuel was running out of this carburetor, so I fixed the floater needle and needle seat. The fuel stays now where it has to bee.
Starting the engine is a big problem. Only playing with the throttle keeps the engine running a bit higher in revs than idle. Idle without playing with the throttle lets the engine stall.
The inlet and exhaust manifold where already mounted on the cilinderheads/engine and I'm afraid, there may be a vacuum leak.
After playing with the throttle, the carbureter is at the inner bottem flooded with fuel. The two front cilinders hardly become warm, the last 4 cilinders get a bit warm.
The nut and special (unequal) clamp between the exhaust "pipe" for cilinder "One" en de inlet manifold "pipe" for cilinder "One and Two" are missing, same story at the end of the engine at cilinder "Six and Five" (assuming the front cilinder is "One" and the rear cilinder is "Six").
Compression on all cilinders seems to bee OK, according the "equal" heavy sound when trying to start the engine.
Does anyone know the Ignition firing order?
Any suggestions?
Thank you in advance and take care of your Pontiac,
Jos
