Hello, I have a honda gx160 engine that powers a pressure washer. I damaged the crank case trying to get the pump off to replace it. While putting on the new crank case cover I pulled the timing gear out!! Since then I cannot get the thing to fire. I've lined up the marks on the cam gear and the main gear but to know avail. Is there a trick to this? what am I doing wrong? Any help would be appreciated. Thanks!:4-dontkno
