Proplems cold starting the engine - advice needed
When cold my '56 M38A1 only starts with the help of a lot of starter spray.
When running the engine idles and sounds normal.
First I suspected the fuel pump to be the cause but that cannot be
because the engine starts properly when warm.
Did you face equal problems? Do you have an advice where to look or check?
Thx.

A well tuned M-38A1 is one of the quickest starting vehicles, even after setting overnight, they will start on less than the first revolution. Is everything on the fuel and ignition system original?

I had a 1952 m38a1 jeep, 2 m151 jeeps.In the winter time when it got down to minus 10,20,30 below zero, the 38a1 jeep always started within seconds of trying.The mutt jeeps were not so.(these jeeps sat outside)

Cold doesn't mean cold in the sense of low F degrees but rather that engine wasn't running for same time. Over here we currently have 70F

Thank you all for your comments. I found the cause: the choke wasn't closing correctly. Some drops of WD40 fixed it.

When in tune, all that is necessary to start a cold M-38A1 is full choke and shove it completely in the instant it fires, usually in less than one revolution if driven daily. Pumping the accelerator pedal is not effective. The "F" Head is a good design.
