ok i think my timing is off.ok is it normal to hear a kinda clicking when you throttle really hard?? say i'm going in 2nd gear and when i step on it slowly nothing but i step on it hard and you can hear some kinda clicking. i don't know if thats cause of the timing or ?? also i did it myself i had a timing gun that had degrees and all that but they had said to put it at 0* did i do something wrong or is it the gun??
