How do I wire a 49cc starter to the motor how do I wire a starter how do I wire the starter to a 49cc scooter

a SCOOTER. year 2000. not cc (LOL)
cloned version of Honda's AF18E/AF16E Dio motor.
Air cooled, 49cc, single cylinder, 2-stroke
Compression Ratio: 7.2:1

it's in the manual. RTM" service manual

there is computer model to calc, this using compression ratio and cylinder volume
but
here is generic list.
my lawn mower is 100psi;. (and mopeds and outboard tiny motors and scooters tiny not 250cc hog scooters)
my old car is 150psi
my newer car with high 10:1 CR , is 200psi
a 49cc engine 7.2 CR is like 80psi.
low and expected. at that CR, 100 max
to get the reading correctly
good guage
fast cranked (kicked or starter turned)
let the meter peak and peak is spec. read peak PSI
and the CR is what matters.
and only on a warm engine, warm/hot not cold
cold is way less.
when warm the rings seat, cold they do not.(well)

go to manufacturers site and look for schematic diagram.
