Hello, i am in the process of restoring my dads ‘66 polara and im at a loss. Originally, I rebuilt the carb and changed spark plugs / oil. It was running for about 3 days in the driveway and now nothing. (Cranks but won’t run ) replaced the mechanical fuel pump with an electric one as well. If anyone can offer any insight I would greatly appreciate it.

 

Got Fuel? - Got Spark at the plugs?
Look down the carb, Work the throttle and see if you got fuel squirting?
Plug one plug, ground the hex head and crank the engine and see if you have spark? If not adjust the points.
