Hello Stuart, can you please show us your fuel filter so i can see it is fitted in the right way
(they flow properly in one direction)

Also it helps us see how you set up the pipes too.

It looks correct, i can’t see how that will stop the bike running to be fair.

It sounds something else has gone off during the assembly  / disassembly of the bike.

Also idle-adjuster is under the coils   or it is near the front carb if korea put a short one.

I can see fuel in the filter, it is flowing. So that leaves out the tap & pump.

However, check vacuum leaks with a carb cleaner by spraying the intake pipes and check air pipes for any splits or kinks  or bends

Also Hyosungs don’t like E10 , the carb 125s will usually make sure to punish the owner eventually when it keeps using e10. So if you have e10 , get rid of it and be ready to clean the carbs by only ULTRASONIC or AIR COMPRESSOR  —- (Rattle cans won’t do the job, they aint agressive enough)
