Hi Javier, the carburetor is the modern one that below has a rubber or balloon that you press, load the carburetor with gasoline and then take it back, the issue is that I am not an expert in this, as I told you it is already well handled ... I left the spring screw in one and a half turns, I screw everything and unscrew 1 and 1/2, another thing above the drum or needle has another screw and I do not know how to leave calibrated, it is also fiddled, the chicler or bubble gum as You say it, I see that on one side it has like a black rubber inside and is fastened with a small spire ....
Those carburetors are a whole subject ???????? .. with the subject of the screw that you speak to me if it is the one that is external to the .. It can be of gasoline or the one that regulates the throttle bell (that is the air) but it is so that it regulates in low .. That I can not guide you to how many turns everything depends on the carburetor .. Maybe a photo helps you screw me talk .. Then you talk to me about a black rubber that I do not know which one you mean .. Have you disassembled the carburetor? Inside he has the black diaphragm that I speak to you and has in the center of it a "little chap" (metal) .. Send photos if you can to guide us better
If you have disassembled it and that black is what I call it a diaphragm that spire in its center touches another spire above and is responsible for closing the gasoline to the carburetor which is seized with a screw very small .. That screw you have to adjust it such that I let the gasoline pass but if you raise (squeeze) this spire manages to close .. If that screw you adjust it a lot, do not lower the gasoline to the "tank" or "drum" .. That you verify it with patience and blowing where it enters the hose of gasoline and seeing that air passes being down said chapits and if you raise the spire should no longer enter air ..
If you tell me that they have touched that screw maybe it is very tight and the needle does not open and does not let gasoline ... Check that in turn if you have a blowtorch put the blowtorch through hole that you find lol .. Less there in that place of the needle because they can get out and get lost .. The rest cleans everything .. That black diaphragm lubricate it in oil before putting it together the same gasoline that is very dry hardens these diaphragms which do not fulfill their function (it seems silly but according to me it is the problem main of those carburetors). And then look at the bowler "the rubber below that you manually pump that is not punctured
Sorry to answer here I do not get or not to comment on the comment on the photo .. I repeat the external screws could not tell you with precision how to regulate .. The q is seen on the side with the spring that regulates a time walking Place it more or less in the middle "after the last tuning is done when you start the same way you would have to start being in the middle. The needle or what I call a needle is the one that opens and closes the gasoline inside the carburetor and if I don't wrong is like a little spire caught by a small screw you just adjust the screw
Maybe I don't understand your question with the needle and it's very difficult to explain it here.
I still can not comment below .. and if I know now what needle you tell me and excuse me the truth that I never had problems with that needle and it seems to me that it is hooked with a "safety" I do not remember that it is screwed .. but that perhaps it is not all right? that is, if you accelerate it does not go up? .. I advise you to assemble it and see what happens
It is calibrated with a screw from the outside .. But once I'm walking .. The truth as I tell you I never had a problem with that needle .. If you have a screw put it in half and try .. Regarding the gum (naphtha peak I say) unfortunately you can not take out yet that in your photo I saw how I had to put a screwdriver but it seems to me that it is not the gum .. The reality is that they can not be taken out that is why I tell you to put the blowtorch on every hole you find ..
Hello Javier dear, I tell you that the weeding was ten .... thank you very much my friend, the adjustment of the carburetor needle in the air inlet, in which it has the small screw screw hidden I have left it in eleven turns and the adjustment of the screw with spring, I think it's air inlet, of being in the middle, I screwed it up one more turn and the machine responds well and has torke ...
the needle that I tell you is the one on the accelerator cable and has a very small screw hidden, when you accelerate the needle is removed from its plastic cavity and drains more fuel, the other internal needle is the one with the floating
Hi Javier, I do not understand much of this but I tell you that it also calibrates and works at rrosca, if I give everything it closes the gasoline pass and if I unscrew it increases the opening and I already read in some forum how difficult it is to calibrate when the They move, can the gum you mention be disarmed?
