Yes i use the marks on magnet,... and yes, is the same, if i turn around 180 degree, is the same... but... i have this strange feeling the Chinese so called racing cam a9, is fault.....

because also when i tried to start the engine.. it was blowing air out in intake manifold.. not sucking (creating vacuum) so something is really wrong

If its blowing that means the intake valve is open during the up stroke or isnt closing fully. could there be something stuck in the valve seat? maybe a missing nut or bolt? To big to pass (A good thing) but small enough to keep the valve slightly open.

Or worse yet, a bent valve?
