Ready to shoot my 273

Just guessing... Timing too low, fuel level in the bowl way too high.
Disconnect the vacuum line to the spark advance in the carb and put a vac' cap on the carbs port. If you dont have a timing light, just turn the distributer slowly moving the vacuum advance in front of the oil sender.You're looking for 16 to 20 before tdc.
Now turn the engine off and look for fuel leaking down the carb and smoke like vapor coming out. If thats not present, good. Now move the throttle by hand and see if the very slightest movement will cause a squirt from the accerator pump on the carb.
If you have a aftermarket air cleaner check that it isn't sitting on/hitting the accerator pump lever or linkage when its bolted down.
Leave evrything as is and drive it. If you get a spark knock under load like up a hill you need to lower the timing in small increments until that goes away.
