Can't get it started

If it is a Thermo-quad type, the accelerator pump has an internal short hose from the accelerator pump to the discharge nozzle. They harden and crack with time. FYI. It is never good/safe to pour fuel into the carburetor. Doesn't matter if it is a Holley or Carter/Edelbrock type. They have vertical bowl vent tubes. Fill the fuel bowls by feeding the fuel through the tubes. Now you can check the accelerator pump. No spilled fluid. I had a friend with over 40 years of under hood experience get seriously burned by pouring fuel down the carb throat while someone was cranking the engine. It backfired , my friend spilled the rest of the fuel on his long sleeve shirt sleeves which ignited and caused severe burns on his arms. Rookie mistake. Never use a combustable to check for vacuum/intake leaks. You can do the same with a spray bottle of water. If you find a leak, instead of the rpms going up with your flammable fluid, the rpms will go down when water is sucked into the leak. Same result to find the leak. One way is safe and one is not. Also have a current, proper type of fire extinguisher handy. You should have at least one good sized extinguisher in your shop at all times. Also handy to have one in the kitchen. We never think about the simple things until we find out the hard way. as indicated earlier, you must find out how hot/high the current is at the coil and plugs. Also recheck the initial timing. Like was said earlier it is normally something simple. Don't assume anything is correct until you physically check it your self. Never assume anything. Good luck with your diagnosing.
