Hi recently bought a 1985 DT 125 in fairly good condition for my son. No leaks, starts first time on kick. however the problem comes in when riding its not idling properly and when reaching high revs it seem to cutout. 2 questions really; Is it compression related? Is it carb related, if Carb, how does one get instructions on setting the carb appropriately. Help
