i checked the timing in m car. 4 degrees. WTF. when i changed it to 16 it ran like ****. so i put it back at 4. the dizzy bolt is right in the middle at 4 degrees. p28 on a d15b. bolt ons. can get the idle to stop jumping either. any help would be greatly thanked.

I also have the D16Y8 pully on the d15b.

there is three marks then just one mark to the right. on the crank pully with mark is TDC?

 

the 3 marks mean min specs advanced and retarded. #1 piston on tbc on intake stroke.

 

so which mark do i put at top dead center? one from the group of marks or the mark by itself to the right?

 

there should be a up mark then 2 lines left and right side of it. those two shoule be alined, and the bottom one should be off the the left a bit by a few degrees. TBC mark aligned with the pointer on the timing belt back cover.

 

that on the d16, d15 those two lines that are alined left and right, tbc marks aligned with the cylinder head upper surface.

 

awsome thanks. i see you have a test pipe. Greedy. how much? i just got one. when i hit 5000rpm all i hear is BUZZZZZZ. so i need to replace it. already have the flange just need the resinator. will this one Buzzz also? thanks for the help
