having trouble with stabilizing my ka

[neogeoss4]

i got my head rebuilt, piston rings replaced, hand cleaned fuel injectors, we put it all back together me and my boys and we cant manage to stabilize the engine... it cranks but it shakes and wont stay on... well it's been a few days and its always the same response, the timing is adjusted perfectly to jimwolf specs, but when we crank it and try to adjust the distributor timing, the engine is too unstable, we hafto give it a lot of acceleration just in order to keep it running @ 700 RPM... i REALLY need some help ... please

Ecu throwing out any codes?

What kind of mods?

[matt4pl]

possibly a tooth off on the distributor. also check for vacuum leaks

Sounds like you have the cams a bit off, what are your compression and vacuum numbers looking like?

EDIT: Also, you cannot set dizzy timing by cranking on it. Just pull it out, set the timing marks and stab it. Then, when you get it running, use the timing light.
