I am setting my engine timing on my B18C1 with aem cam gears and the timing marks are never perfect. . Any help or opinions would be appreciated. When i removed the distributor the cam is perfectlystraightup and down which i believe they are correct. for a pic just post i will email it.

 

compare the stock against the aem gears to make sure they are right, my friend had a batch of gears for his gsr they were not correct, and then go from there
