yikes… soooo did you purchase an entire harnass for the turbo motor or did you do your own creative wiring? what is “stock” and what isnt?
rotary motors are notorious for flooding when they are running “correct” so while the motor does flood, it may not be your only problem…
are you sure you have spark?
remember to get the motor to run you need air/fuel/spark… you said you are getting backfires so that probably means you are gettin g spark… but it may only be intermittant… the coils on these cars like to fail sometimes… so maybe a coil is bad or wired incorrectly… have you run a compression test on teh mtoor? it is a rotary after all…
