232*-35*=197* duration. Is a proper method of measuring the induction duration?

I can't get ATDC measurements because the piston gets stuck.
Yep if piston still tight in the sleeve this is right method to mesure. In your case induction is open @ 35 ABDC and close @ 52 ATDC with total duration of 197 deg of opening.
As a sugestion-opening is OK, but closing is too early (for on road engine) at list by 5 degrees.
