Ernie, not a factory option or accessory, just an "improvement" some owners chose to incorporate.

I installed a starter button in my 47 Custom. I simply took the wiring that went to the carburetor switch and connected it to the starter button mounted on the lower edge of the instrument panel. Reason for the starter button was to provide for more flexibility in starting the engine with an independent accelerator pedal. It worked fine. No permanent changes were made. The next owner could easily reconnect the carburetor switch because I kept the wiring with its original terminals and length. JWL

Hard start when hot:

If the carb is hot enuf to boil the gas out of the carb bowl then the rest of the engine is hot enuf to boil any gas that might be forced over into the intake manifold. "Flooded" but only maybe for a few seconds.

I have hard start when hot too on my 56 Exec.. Somtimes it will start by holding gas pedal to floor (but still a bit slow). Other times with no attempt to hold gas pedal to the floor it will still be difficult to start. No ryme or reason to it.

Summers comming so i will carry a lighter fluid can full of gas to squirt down the carb if the problem gets bad enuf.

Bottom line:
If carb is hot enuf to boil out the fuel then the rest of the engine is even hotter yet to boil out any fuel overflowed into the engine during intitial perulation. No fuel.

So constant cranking of the engine is needed to pump the carb bowl full again.

As for the auxillary start button:

The carb mount starter switch is probably about as inconvenient as the modern day clutch pedal saftey switchs. Clutch must be depressed before starter will engage.

I have 2 off road service trucks, one with no doors nor windows nor windshield . Quite often need to start engine by simply reaching over the hood of the truck or across the passenger side to start it. The clutch safty switch is disabled.

SO those that converted to auxxillary switch probably did so for some similar convenience.

Always looking for more info about my 1951 Packard 300, so when looking up the Carter WGD 767S I found that the 1955 Pontiac Safari used what was almost exactly the same unit with different ID numbers. It is more detailed than some sights and may be helpful when rebuilding or adjusting. Here is the site:

That is the most comprehensive service info I have ever seen for a particular carburetor. Very useful, thanks.

I haven't had this on my Packard. I ran into this on several other vehicles. On Ford trucks we would replace all of the ground cables and clean the connection spots on the chassis and frame. Worked every time on Fords. On Mopars we would check the timing. They will run great with lots of power. When you turn them off sometimes they will not start until they are cooled off-especially in the warmer weather. Just a couple of ideas.
