First time for everything . I've got an engine called an Xingyue Xy139 - 7 (i think it may be chinese ) haaa .. a neighbor asked me to fix so i found that it had a stuck ex valve so i got that fixed but the issue is there is no markings on cam, crank gear or block casting for timing ...nothing. also it uses a single cam lobe for int & ex with rocker arm type lifters no luck on line for info . This is a somewhat new engine . went to the Xingyue website with no luck but found out they manufacture everything from spatulas to personal " happyness " products. Soo if anybody has a clue how to get this thing timed it will be greatly appreciated. Thanks
