CAN A DT125 CARB FIX INTO A DT175 ?

HI...I HAVE A 1983 DT125 AND RECENTLY I BOUGHT A 1980 DT175 WHOLE ENGINE BUT WITHOUT THE CARBURETOR. THE ENGINE FITS COMFORTABLY BUT WHERE CAN I GET A SUITABLE CARBURETOR, THINKING OF USING BACK THE OLD DT125 CARB AS REPLACEMENT. SOME SAYS MIKUNI VM24, TM24 AND ALSO VM30...I DONT WANT TO BUY AND LATER FIND OUT IT IS NOT SUITABLE...CAN SOMEONE IST ME ? THANKS IN ADVANCE !
