timing help
I've been having problems adjusting ignition timing for a while now, I've replaced parts adjust and inspect everything.
I've changed timing belt covers, cam gears, crank pulleys, but I still can't get my timing to stock specs at idle moving the distributor all the way to the front.
what else could be the issue? I've adjusted it by hear and its at the center, with the timing light its completely off.
please only sensible replies.
JD, xenocron. leed if you are still around

Have you double checked the cam timing itself? Pull the crnak pulley, and check the crank gear at the oil pump and then check the cam gears to make sure they are indexed properly.
Is there anything odd about the block and head combination? Any heavy milling on either?

Re: timing help
Aftermarket cams aren't neccesarily in time with timing marks at 0,0. If there has been milling/decking even stock cams can be out of time at 0,0.
You have a B-series, as long as the lower timing cover fits you can run any crank pulley and it'll line up correctly.
If you can not physically turn the distributor far enough to go into ignition time that's pretty fucked. There's ~7-9 degrees travel in either direction, with respect to the distributor centered.

everything is in sync with each other all the marks on the block, crank gear, cover, head are all in the correct position. the head has not been milled.
I am wondering if its just a issue with the ls/vtec process.

Re: timing help
Do you not know that if your cam timing is off your ignition timing will also be off?
Just because your timing marks line up doesn't mean everything is REALLY lined up. You need to degree your cams to verify that.

No it isn't a problem with the LS/VTEC process.
Let me ask a silly question.
How are you setting the ignition timing? What type fo timing light are you using? is it a standard one or a dial back timing light. Which marks are you using on the crankshaft pulley?
