Unstable relief

Gentlemen, please if anyone knows, I have a Jeep Daihansu Rocky Year 86 The problem is that the relay when being in operation is unstable, everything they have told me is verified and corrected, they change the ignition for an electronic one, that if it is still carbaded, the spark plug cable, spark plugs, etc.

Hello PC, I ask you to detail everything that is done regarding this problem and if it is carburetor or injection I expect your answer.

Ok..The Jeep is carburated and has a 2000cc Model 4y Toyota engine, the conventional to electronic ignition was changed, the carburetor was checked and packaging, float cutting valve, spark plug wire, spark plugs, spark plugs (dense).
What is not changed and I do not know if it is related to the problem is the electrical click that it has. The other is told that it may have any air filtration in the brakes, I do not know if this will be real ....?
Well that is as what I have grateful for any idea why the release is unstable.

Greetings and thanks in advance

RECOURD OF THE ELECTRONIC CHICLER CAN BE YATED THAT IT IS DIRTY DOES NOT COMPLETE ITS ROUTE THEREFORE A DEFICIENCY IN THE PASS OF NAFTA (if he does not open or close correctly, you could have much or little naphtha flow).
Regarding the brakes if, it can be, but beware only the hose that goes from the servo to the multiple of admission that is the empty to help the servo, if it has a fissure loses emptiness and tends to break the release (check the entire hose and its couples), a test puts the jeep ongo Q have a sucking air and then check everything that corresponds to the air intake, example: the carburetor cover, the pipe that goes to the air filter container, and the air filter container. Test and then tell me. SLDS

Ok ... I thank you for the tests you tell me and I tell you ....

Greetings
