1957 Roadmaster Starter Switch

If it cranks when you press the accelerator, the switch is working.

Fuel in the carb doesn't necessarily mean there is fuel entering the cylinders.

I would check compression first.

Also check for clean, tight engine-to-body and engine-to-frame ground straps.

 

Check spark plugs, plug gap, correct firing order.

In my experience, the timing needs to be right at spec (5 degrees BTDC).

Update:

Sorry it took so long to finish this.

After going thru Ignition Timing, Spark Plugs, checking for Vacuum Leaks, Fuel Delivery!

Finally the car would start with the carburetor choke on. Which before the rebuild would start with out the choke on.

After this, the engine developed a really bad hesitation flat on its face, stall out from a dead stop.

 

Accelerator pump was giving a shot of fuel, as you opened the throttle just not enough. Changed accelerator pump and spring (A slight shorter spring) 

Up and running again jeeze-o-pete! 

 

So, I rewarded her new shoes 3" White Walls!

Older material (except for leather) isn't ethanol-tolerant and could cause trouble, if age alone wasn't to blame.  The accelerator pump diaphragm in my Riviera lets me know whenever it detects ethanol in the fuel!  I have a new one (blue colored) I bought awhile ago to install , but since I run ethanol-free 99% of the time I haven't put this task on my 'must-do ASAP' list...
