I had the same problem with youand it's comp cams fult

I have set the timing on 0 and when I try to crank the engine it's backfire from the throttle.....I thought it's need a spcial degee or something.....but it's won't start

finally I after 2 weeks of trying I found the's the comp cams timing gear #2100

it's give you a totally diffrent degree of the 350 engine

usually when you matching the two points on the timing gear the piston #1 must be on TDC "new lesson to me" but with comp cams when you matching the points the piston #1 is going down with open intake ..or intake stroke and that's why it's back fire when you try to crank the engine

comp cams is junk is poeple say and now I belive they are junk

it wasting me the money-time-work so you should match the old parts with the new
see the diffrent between the comp cams gears"left" and other brand with a correct timing "right"

I try the free host but won't I upload the picture in my flickr account

good luck and contact the comp cams....I think they replace it ...I,m not yet contact comp cams yet
The gear set on the left has 3 key ways to allow you to set the cam advanced or retard you may have just used the wrong key way, check the instructions again
