Engine runs fine but seems to seize after wot

Yes the engine is physically not seized. I checked the spark in open air. What would u think the resistance should be on a accel super stick coil? It's getting fuel for sure. After trying to start for so long I checked the plugs and they are wet with fuel. Carb is good and so is timing chain set. Coolant is free from oil and visa versa. Battery is charged and still can't start. I think I am having to get a starter or at least have it tested.
