Installation of the gas train itself

hello I have asked to replace the gas train from my scooter. so the most important thing first… I have a johnway china scooter, which is identical to the Rex 50 scooter. So far I have bought all the spare parts from this vehicle and it has always fit 100 percent. now I want to make the gas train repair. I am not a professional in it and actually have not much to do with scooters but still some experience with screws so far I could fix the tires sow ohl change the brakes independently without any problems I have now seen that the rope hoist is torn directly at the handle. of course, it is not possible to repair it. I will order a new one now costs approx.15€. now my question: what length does a rope hoist have to have? I mean that must also fit exactly when I pull the train down to the gas, there may be no space between the train or else the train does not pull. I have already the old train on the handle outside, only has to unscrew it down The places where I have to go along the train I have already freed and get quite well. Just as I said, I don’t know how to do this with the length… There are different, and before I buy what I prefer to ask about My workshop I have already asked what that would cost and it was at almost 80 euros. Unfortunately, there is no other workshop nearby. And I find the amount too much for a scooter for which I needed 300. Sell I guess I can’t do it because I don’t get anything for it. Although it’s going well except for the train. So I’d be grateful if you answered the above question for the time being then I’ll go to the purchase and make it. Of course there will be one or two questions that I can ask but only then But if I look at all this it doesn’t seem sooo hard to change it or? One better thing if I’m totally wrong. t pay attention to spelling and grammar but I wrote all this with the tab Many greetings Here are some pictures: Here are the links of the lever (kA if the ne role plays):http://planetoli.de/wp-content/uploa…o-1024×768.jpg The end piece above:http://planetoli.de/wp-content/uploa…1-1024×768.jpg The end piece below in the engine:http://planetoli.de/wp-content/uploa…27-2059401.jpg Here is the point (of the crack) at the lever:http://planetoli.de/wp-content/uploa…427-210046.jpg
