hello , and thanks for the nice guide . unfortunatly i broke one of the adjusting screws , and i could not take it out to replace it . i had to change the whole rocker arm shaft with all components attached to it , but when unscrewd the two head sylinder bolts , water came out of bolts place , is it a problem??? should i worry after placing the bolts back ???

what could happen if exhaust system has leaks ???

Hi Ricardo At last i found one problem : idle fuel air jet is faulty ( the on in the photo ) . the narrow tube is long , it should be short . replaced it with new one with a shorter narrow tube . now when i turn mixture screw all the way in , engine doesnt stop running , but it runs in low rpm . at least i can set mixture screw very much better than before . Now there is another problem : when the engine is cold , i start the engine , choke rises rpm very good , after a minute or two engine suddenly stops running , i try more than 10 time after that to start engine , then it runs , some times i press fuel pedal the engine stops running . when engine gets a little bit worm , everything goes ok , and all problems gone . Any advice please ????

yes i did change the enrichment valve with a new one . and i checked the vaccum using smoke : the only place was leaking smoke is the axe of the throttle valve note : if i turn the idle screw all the way out the engine stops running , and if i turn the choke flap to block air passage the engine also stops running , and if i take the electric cable out of the cutoff valve also the engine stops runing . yesterday i had a look inside the stage 1 while the engine is running , i could see the throttle valve flooded with fuel but i couldn't locate where the fuel comes from . i checked vaccum unit of the distributor , it's keeping pressure . i also took out the hose of servo and blocked it's hole in minifold , tried the mixture screw , still the same problem . i'm really tired of this car . and i do not know what to do . i cannot find new carburator . my carburator is piece of s*** . i think selling the car is my only chance now.

hi Ricardo good news : no more black smoke in the exauhst bad news : mixture screw all the way in ( blocking mixture ) , and the engine still running . car is running smoothly powerfully . could it be the vaccum unit in the distributor ????

hi Ricardo .. finally i found where the problem is : mixture screw , i had to change it two months ago , because it was broken as you see in the photo , i brought another one , and discovered yesterday that it doesn't block the mixture when it's screwed the whole way in , you can see the difference between the two screws in the photo , now i'll look for new screw that fit in my carburator , i wish to find one , thank you for your help

my car is 1998 , about 200,000 km . it's written on the side of the Carb ( jikov , made in checkoslovakia ) my car ran well only one time and for about one week , it happened when i fitted the hoses in right positions ( they were fitted wrong ) today i tried rotating the distributer : black smoke got lesser , but i didnt have luck with the mixture screw . note : when i bought the car about one year ago , a mechanic changed piston rings , they were faulty

Hi Ricardo I have doubt about enrichment valve , looking at the photo you've posted before , i see 5 holes in the valve and 3 holes in the gasket . my valve has only 3 holes and the gasket also 3 holes . why is that ? And the holes should be placed up or down ? For the valve and the gasket .

I checked for vacuum leaks , fixed them all , same problem with mixture screw, black smoke increesed . I didn't replace the float needle , but I don't know if the former owner did ? Can i measure fuel level in float chamber without removing the carburator out? One more notice : when i push the brake pedal in , or out , rpm raise from 800 to 1100 then goes back to 800 , is that normal ?

hi Ricardo i did everything as you told me to do ( resurfacing , using rienzosil , removing PDU , blocking the hose with a ball , removing TTV ) ... but i still have the same problem which is : i turn the co mixture screw all the way in and the engine stays running . i have black smoke from the exhaust . what should i do now ???? do i have to check the servo pipe ??? or anything else ??? thank you for your help

Hi Ricardo Here's what happened with me : I found that the vaccum pull down leaks , now I'm looking for a new one . The good news that I found rienzosil from victor rienz , the bad news that I couldn't find a new vaccum pull down till now, i tried to deassemble the vaccum pull down , but it can't be repaired . Im in real trouble now . Thank you for your help , I'll let you know if something new happened.

i can use the gray rtv silicone alone ? or with cardboard? and if alone i should make a 2 mm continuous bead ?

hi Ricardo i found this gray rtv silicone note : thinking about rubber , what about making gasket of internal wheels shown in the 3rd photo ????

you mean i cannot use the liquid silicon ??? ok thank you a lot ... i'll tell you what happens with me ..

thank you very much Ricardo , i think no more clarification is needed . now i'm looking for silicon sheets . my cousin told me that he can bring me a tube of liquid silicone that is heat resistant , is it right to use it or not ?( in case i couldn't find sheets )

thank you Ricardo for the great informations....but i have some questions plz: 1- sandpaper should be soft or rough ? 2- can i use gasket maker liquid instead of 'liquid gasket' from Victor Reinz ?? 3- do i have to put the sealant or gasket maker ( if i can use instead ) in touch with the manifold and the carburator ? 4- i dont have torque meter ... what can i do instead ??? 5- do i have to put sealant on the gasket between carburator's upper and lower parts ? 6- for silicone rubber or viton sheets ,do i have to resurface the carburator base ? 7- do i have to resurface the plastic spacer too ? or just the steel base ??

i have the new steel plate and plastic spacer ...

hi Ricardo . and thank you for your encouragement , im far from war zone indeed , and Syrian people will defend our Syrian against terrorism for my question : actually i have a problem in my carburator , which is that i turn the co mixture screw all the way in ( closed ) and the engine stays running , and i have black smoke and heavy fuel consumption , what i did was the next things : 1- cleaning carburator and changing gaskets 2- changing jets 3- new carburator base with new gaskets 4- new enrichment valve 5- changed all hoses in the carburator note : when i close starter flap the engine turns of .... i have doubt about choke pull down as to leak ... but i dont know how to disassemble it .. thats why i ask about it thank you for your help

i just want to ask you is this (enrichment valve diaphragm) or (vacuum pull-down) ???? because the (vacuum pull-down) could not be deassembled ... am i right ???
