perhaps a Tiico engine is differnt,
but on all other VW engines, it's not possible to put the distributor in 180
out,
but it's easy to check if that's suspected.
if you can tell when the valves are on TDC to fire, you can see if the
distributor rotor points to the right cylinder.
Firing order is correct ? It's possible to make that 180 out, or worse.
and .............*check the basics* .......
every time things don't make sense............go back and check the basics,
timing belt alignment, compression, intake leaks, intake air boot, wiring
and hose connections etc. etc. etc.
I've had to go back and Check the Basics five times
sometimes..........before I found 'the thing' that was keeping it from
running.
for sure, just getting it to fire up at all.......there's a lot of leeway
with the timing there. If anything ........advance it too much initally, to
get it running.

You said no flooding, but are you getting ANY fuel? If there is
fuel, I would suspect your distributor is 180 degrees out. A gasser
should start as much as 20 degrees +- of where it should be.
