Timing:too far advanced, too far retarded

The last thing I'm goign to check before I get a new motorcraft 2100 to replace the old I rebuilt is the timing. As is stated above what happens when the timing is too far advanced and when it is too far retarded. I just checked it quick tonight and it looks a litle retarded(the mark on the pulley was a little bit before the 9 degree mark on the scale. The engine runs super lean and it has absolutley no top end. I have eliminated everything else so it is either the timing or a mc2100 from a ford V6 just will not work on a 258. Thanks

I need to get a girlfriend I'm getting to close to my jeep.

Re: Timing:too far advanced, too far retarded

If the timing is too far advanced you'll tend to run hotter. If the mixture is too lean you'll run hotter. If the engine runs fine, except for the lean condition... then it's probably not running too far advanced and I'd vote for a problem with the jets. They may be too small for the amount of fuel the engine requires. Check that out.

What ever you do... do ONE thing at a time and check the results before you go on to fiddeling with the next thing.... you can get lost real quick chasing this problem. Keep it simple and easy to retrace your steps by doing one thing ast a time and confirming the results.
