Would it be possible to post a pic of the literature or a link to it? Would be interesting to see.

This info is from Jon Hardgrove at The Carburetor Shop:

"HARD STARTING, COLD
Difficult starting a vehicle that has been allowed to sit for a number of days (that will then start well the rest of the day) is often caused by modern fuel. Modern fuel begins to vaporize (evaporate) at a much lower temperature than fuel before the 1970’s. Once the engine is shut off, the fuel in the carburetor bowl begins to evaporate through the bowl vent. If there is no fuel in the carburetor, the engine will not start. Pumping the footfeed during this time simply prolongs the agony, as the accelerator pump will pump the fuel into the engine, but in amounts insufficient for starting. If you have this problem, try priming the carburetor by using an eyedropper and filling the carburetor bowl through the bowl vent prior to cranking the engine. If you do not wish to prime the engine, crank the engine for 15 to 20 seconds WITHOUT PUMPING. Then stop cranking, pump the footfeed 3 or 4 times, release it, and then reattempt to start the engine. Priming eliminates excessive wear on the starter. Another possible solution is the installation of an electric fuel pump. If an electric pump is installed, check local, state, and federal laws about wiring; and pick a pump with pressure not exceeding that of the original pump."

FWIW

Thanks, good info. I have read that before but was interested in the "factory" literature that was previously mentioned.
