Hi, I have a good spark as I rigged up an inline spark tester this is what led me to think the plugs were black so I pulled one and confirmed my suspicions. I haven’t attempted to pull the other yet, access is tight and knowing my luck I will break something…Are you better to let any fuel in the cylinders evaporate first? Otherwise if its flooded you would just be putting new plugs into flooded cylinders.Hello, I run an Edelbrock 1404 on my 3.5 V8 if ever I can find a good set of HIF6 SU I will change American fancy junk.
Start by checking you have a spark with a new plug, Then change all the plugs for new ones and set the idle screws to 1.5 turns out
If it has sparks and still does not go check you have fuel if necessary remove the carb and check floats, also check ignition timing has not slipped
Your rods are not on this chart very unusual

When this issue started I screwed the idle jets in and backed out 1.5 turns but she’s not been running since but that’s obviously not related. I’ve not checked the timing, not much idea on how to do that yet.
I don’t know the jet and rod arrangement, I will reach out to the previous owner and see if he knows.
There is no choke connected, used to be 2 pumps of the throttle and she starts.
