Okay thanks for the replys.. : )

I try to get another ke-jet fuel distributor to test if will help, i will go ms-efi later this year so i i want to put car working as minimal cost as possible. I did read somewhere there is some adjustment screw in distributor under the fuel pressure regulator? Should i try adjust it first, or replace directly whole ke-jet fuel distributor unit?

Imagine what would been happen if i dont have afr meter

ps. If you have 100% sure working fuel distributor unit pm for me
