again nothing

Trying with adjusting the screw on the throttlehousing and fueling on the meteringhead, but just some bangs, but no good running engine!!

Changed leads, but no use
Disconnected dump valve, but no use

I got on the dissy the right-top one to the first cilinder; left top one to the third; left bottom one to the fourth; rightbottom to the second cilinder

That is the way it should be isn't it? or can it be that the roter is put in 180 degrees wrong?

I still have lots of backfire..

Maybe my crankshaft gives me problems. I have a Piper cams 285T in my car and the timing is just for running in set like normal! Should i change it? and if i change it should i set the arrow on the pully a little bit to the left or to the right?


Please Please help my guys!
