I have a huge problem with my Peugeot SV. My scooter hardly starts after a service life of 2-3 weeks, I have to press 10 ml of petrol into the float chamber each time with a syringe over the drain screw so that the float chamber is filled again, only then it starts up. If I then put it back down and shortly afterwards it starts up without any problems, only if I leave it there again 2-3 weeks he has start-up problems again, these problems exist first since December 2013, although I have my scooter already 20 years, my scooter is built in 1994, so already a little older. So I ask for help with the above mentioned problem, the problem that my scooter starts very badly after 2-3 weeks of service life. Today I had the float chamber run empty myself, I have held a bowl under the drain screw the drain screw is opened so carburettor the gasoline out of the shimmer, running out as this was empty I have the After about 10 seconds he ran organs without problems, i.e. it cannot lie on an empty float chamber alone. I would also like to know how can I use the petrol pump way over my scooter is a vacuum pump because the tank is below the carburettor, check if it still works properly, because in December 2013 this also had no more fuel transported, therefore in December 2013 I started to use the gas pump. November 2013 already the hose from the petrol pump has filled the carburetor (the float chamber) with petrol over this hose, then the scooter jumped on without any problems and I then pulled again while the engine ran the hose which leads from the petrol pump to the carburetor to see if the petrol pump now conveys petrol what it did, the petrol pump stimulated impulse-like gasoline blows direction carburetor, I also don’t know whether this is normal or not, also how much the petrol pump umpe must be promoted I do not know. I therefore also ask for precise instructions how I can check this to ensure that the petrol pump is not defective. I hope now for as helpful answers as possible.
