GRR.. only revs to 4000rpm - WTF?
 

My car still seems to run rich - at least I think so, and it has a starting problem - it doesnt like to crank over - mebbe starter, mebbe battery. Anyway. People have suggested fuel filter, but if it backfires and bogs - shouldnt that mean its running rich?? And if it is, how can i tune the efi to run a little leaner?? DAMN TROUBLES!

Sounds like you may have a cloged cat.

Yeah I would check the cat...

Did you put a fuel filter in it yet, as you had mentioned on this post,

not yet, weather's been freakin cold... I 'll probably throw one in for the helluvit, but to me it doesnt seem like not enuf gas, it seems like too much gas, not enuf spark... I'll check plugs an everything later when it warms up, but for now, The Mighty DATSUN 510's running hard - 30 yr old cars are fun to bag!

Check your catalityc, knock on it and if you hear some rattle gutt it and/or replace it.

YES!
 

Fuel filter and plugs- $100 cdn - fixes it. Runs great... Now I'm happy.... but I need an 1989 +newer alternator in good shape, low kms.
