Default 87 indy 400 won't run

I have cleaned the carbs and reset them, new plugs. I have cleaned the air filter. I have pulled the head and have redone the pistons. I have spark, gas flow, coolant and oil. All lines are clear and working. I think I have done everything. What I don't have is an engine that will start!! It was a 2 puller before this season. I would welcome any suggestions. Thank you.

Does it run (briefly) when you squirt gas directly in the cylinders?

It did for a brief time. This was done while trying to "prime" the gas pump. Once the gas was in the pump and lines, it ran for about 10 minutes. I shut it down to replace the belt, hoping to take it out, but it never started again. Now it does nothing. Very frustrating.

Perhaps it's flooded now - or flooding ltself when you try to start it. You might be able to clear it out, if so, by holding the throttle wide open when you pull. Then you have to determine the cause of flooding if that's what it's doing. Usually it has something to do with the inlets failing to seat properly - could be dirt or debris in the inlet, or ice in the bowl or inlet. Ice usually ends up in the jets though when it gets in the bowls.

I had the carbs inside the house over night, so I hope there isn't any ice in them. I will pull them again and check for dirt and ice and let you know if that helps. I will also check the bowls and seats. Thanks for your replies.

I checked everything and it looked clean and ice free. I put them (carbs, bowls etc) back in and it started on the first pull. It ran for about 5 minutes, fairly well, and then it stopped. I pulled several times and nothing. Just like before. Any suggestions, again?

Just before it stopped did it start to run poorly with a lot of heavy exhaust like it was choking itself? Are the plugs gasoline soaked?

Redone the Pistons? You want to clarify that statement for us? Did it pull over harder ( more reisitance) after it ran for 5 minutes and then stopped. If so, that's not good. If not, then I would look at the fuel system, a sled will run about 5 minutes on fuel in the the float bowl, and if that fuel is not replaced, the engine will stop. Causes, fuel pump pumping, but not enough volume to keep up. Another, fuel inlet needle and seat not flowing enough, but you said those had been removed and cleaned, right?

you need to figure out if it is getting to much gas or not enough. did you have the pistons out?if you did, did you put the arrows in the right direction? if not it might have low pulse causing your fuel pump to work very little..

(If the pistons are backwards, it'll be better if it doesn't start. The rings won't last long before they hook the exhaust ports. The pump should still work okay until then, though.)
