throttle body sync issues

okay so the other day i got my morgan tbs in the mail and i tried to sync it and ran into some issues (gen1 2005)

so my first question is do i first set the 3rd cyclinder to 25cm and adjust the rest then or don't touch it people seem to have different opinions about this

i got them mostly synced up but cylinder 4 i can screw it all the way in and out without it really changing it drops but it doesn't go up. cylinder 1 is all the way in for it to line up but it's a bit of a given that the screws shouldn't be all the way in or out. what causes this exactly?

what i did ran the engine till it was warm about 2bars then turned it off then removed the rubber tabs on the nipples and hooked up the throttle body sync since 4 was the lowest i adjusted that one first once i saw the screw could be turned all the way in without changing anything i went to 1 and 2

i wouldn't be surprised if the tb is dirty or the injectors got some blow back from when the engine skipped timing
