Packard 110 from storage - carburetor

Just popping in

I am having difficulty restarting my 1941 110 packard after 50 yrs storage. I have spark and engine turns over fine; I rebuilt the carburetor with a kit but find only one needle screw adjustment (for idle) - I am used to carburetors having 2 needle adjustments (idle and load). Is there a second adjustment internal to the carburetor or are all the "load" adjustments made externally at the throttle shaft?

Thank you,
Gene

2 needle values is for two of four barrel carburetors but never on a single barrel! Be sure of the obvious: to use only clean, fresh gasoline and, if using the stock tank, that it and all the lines have been thoroughly flushed. Also replace the rubber hose that connects the fuel pump to the chassis feed AND rebuild the pump itself. The old rubber parts can't handle modern fuel. The service/shop manual should be here in the Literature Archive.

The main jet adjustment on many mid to late 1930s cars is automatic, typically controlled by a stepped or tapered metering rod located in the jet orifice. The metering rod is often linked mechanically to the throttle shaft or it may be regulated by a vacuum piston or diaphragm.

addendum: FYI I rebuilt the pump and replaced the hose that fell apart - I am getting gas to the carb - gas is less than a year old. Gene

The gasoline may be the issue. Modern gasoline is designed to be held in a non-vented tank, and it may deteriorate more quickly in a tank that is vented to the atmosphere. In addition, the tank may have old deposits of gum and varnish that the gasoline has dissolved. If you have correctly timed spark and fresh fuel, the engine ought to start and run, assuming it doesn't have stuck valves. A compression test will reveal stuck valves.

thanks again TxGoat, Will give it a try with fresh gas. FYI: valves appear to be working - I get 90 to 100 psi with plugs out; not as good with plugs in ~60. Hoping that will improve if I can get it running. ? Gene
