I know it is on the right stroke and everything I even tried the other, but like if I give it WOT then tried to start it and then stop and drop it to 25% gas it like goes put put put put. And it I don’t give it any gas or just leave it at WOT it just goes put, So……. IM stumped… I don’t know what to do know.. I checked to see if all the spark plugs are in the right order. I checked to c if they are getting spark. And it all checks out…

Have you checked the fuel pump and to see if you're getting fuel in the cylinders?
I mean, recently - after you cleaned out all of the fuel from before?

FYI most factory ECU's will cut fuel when the tps reads 100% (ie floored). This is a way to tell the ECU it's flooded and to stop injecting fuel while cranking.
