timing issue
 

So I am trying to set the timing since I was tooth off...the engine backfires sometimes mostly while granny driving. I set the idle at 700rpm and the timing to 12 degrees. I heard if you got the head resurfaced you have to compensate for it. Any advice? :017:

Did you fix it so it's now lined up correctly?

If you shaved it over .080" then you need to use shims.

If the timing is truly set to 12* BTDC and it has no power, start with reading the spark plugs.

True no power. It ran amazing at 10 degrees...sight misfire would be not setting idle right have something to do with it?

...and yes lined up correctly thanks to you lol

Is this a turbo or n/a?
If it's n/a, initial timing is 8* BTDC, with vacuum advance disconnected.
If it's a turbo, initial timing is 24* BTDC with TPS disconnected.
How are you "setting the idle" ?

It is NA. I raise the rpm to 2000 for 2 min. and adjust.

If it's n/a, initial timing is 8* BTDC with vacuum advance disconneced And the Gray connector thats plug in the IC unit on the distributor!!!!

I almost :icon_hang: on timing issues

seems i am having the same problem with the timing on my 83 zxT engine and will need to adjust the timing on it.

Where can I find a "How to" for setting timing? Ive been through the haynes and a rebuild book for the L28 and still nothing. Ive also been through the zdriver and zcar forums and find nothing. Any pointing in the right direction is greaty appreciated.

Distributor timing: Haynes manual pgs 26-27, 44-45

Timing chain (crank to cam) timing: Haynes manual page 77.

I've also posted Haynes / FSM scans on both of these many times. :D

Im reading it again. Are there any videos on it? I seem to learn better by seeing what I am supposed to do.

Which "timing" are you asking about? Distributor or timing chain? (this thread is about lining up the timing chain correctly)
