L28 stock timimng questions

[Khaserwolf]

Ok i recently rebuilt the motor on a 78 280 Z, with L28 in it, The ignition set up is stock and the car runs but it sound like it missing between 2000 and 3500 rpm and when we took a timing light to it. well.. lol it reading off the timing marks (sever retarded timing) lol. So my question is

1) what should the timing gun read, in other words what is the stock timing degree it should read. (plz forgive my terms, im new to some of these fields)

2 I learned how to cheak to see if the TPS or (throttle positining valve), but i dont know what is the normal resistace it should be reading when you cheak it with a multimeter.

 

Any suggestions will help

You can't go wrong here - http://www.xenons30.com/reference.html

 

The EE and ET chapters will tell you a lot about your timing. The TPS is covered in EF. Once you get these figured out, you'll probably have more problems to work out so it's best to have this on hand.

 

Kind of surprising that you rebuilt the motor but you're new to ignition timing. Just saying, it's interesting. How did you rebuild the motor without the FSM?
