need help have a 91 honda civic dx. stock d15b2 timing seems off. so i had to move the came gear over a tooth for me to get the timing marks to be right on the pointer when i check it with a timing light. if i line it up tdc. i have to adjust the dizzy to all the way retard and the red timing mark doesnt even line up with the pointer. also after warmed up it kinda shakes and shudders on idle.

Make absolutely sure that the cam gear is in the correct position. What mark are you lining it up to? TDC or the three timing lines? Make sure that the cam gear marks are parallel to the top of the head. Remember that the head itself slopes down slightly in its position in the engine bay.

yeah ive made sure its lined up with the head and that the tdc mark on the crank pully is lined up with the pointer on the timing belt cover. when its warm and the jumper is on i check it with the timing light and i cant get it to line up.
then i moved the belt over a tooth so the tdc mark is behind the pointer of the timing belt cover. after that i use the timing light and i can get the red mark to line up for the timing. but it still runs like it is being pulled back or hesitant to accelerate. i notice the belt flaps for a bit when i rev it then straightens out. i dont know would a loose timing belt make the car shake and vibrate alot and feel a lag in acceleration?

Dude you didn't tension the belt. I had trouble with timing too a while back. After you have the can at tdc and the crank at tdc, put the belt on, then put the timing cover and the crank pulley on. After that, make sure your still at tdc, And tighten the crank pulley bolt tight enough without disturbing the timing. Then rotate the crank pulley counterclockwise WHILE You put your hand on the camgear ( your hand has to push down on the belt while you tension the timing belt) I'd you do it correctly the timing belt will tension up nicely without moving the timing marks. After you tensioned it up, rotate the crank at least 2 full revolutions and make sure everything lines correctly at tdc.

Here's the OEM Honda repair manual on setting the time and tension correctly.
http://www.carenthusiast.com/crxuk/C...hop_Manual.pdf

It is page 63 or 5-17. The two pages below it also give off some information. I'd suggest you torque the adjust bolt, 33 lb-ft. I remember I kept on having timing issues because I would tighten it with my socket wrench. I then decided to torque it to spec and ever since then, it hasn't came out of time.
1. loosen adjust bolt and make sure everything is TDC
2. spin the crank counter-clockwise three teeth and make sure the head/crank didn't move a little bit.
3. torque adjust bolt, 33 lb-ft.
Done

what kind of timing light are you using? - if it is just a strobe, you line up the red mark with the pointer - if you have a digital light where you set the light to the advance you want, say 16 degrees, you then need to line up the white mark (TDC) with the pointer or you can set the advance on the light to zero and check using the red mark

It's just a cheap harbor freight strobe timing light. But today I finally got the tensioner bolt loose and tightened it. And the belt is firm doesn't flap or anything anymore. But it had a slight hesitation when I first step on the gas. But as for the timing. it seems as close as I can get it. When I time it with the light without jumping the jumper. It is right on the red mark. But with the jumper it's kinda off a bit. I'm gonna check again tomorow. TDC is on point when I turn the crank and lined up with the head.

You can only do ignition timing with the service connector jumped man. If it's still OBD-0 and stock engine wise, it should be right in the middle with a few mm towards the radiator. I scratched a mark on the top the distributor bolt and head so if I take it off, I can always put it back in the right spot.
