Hi
I agree with all the previous comments. May I add the following…..
On the bright side, you have it running at high revs so there can’t be too much wrong with the engine itself!
How was TDC established? Flywheel marks are not always reliable. Best to check with a marker through No 1 spark plug hole (of course ensuring you are on the compression stroke).
Fast running smacks of an air leak. What manifold are you using and were the faces true before bolting it up?
Good luck, you’ll find the problem and when you do let us know.
