It is carburado so you will have to do if you have an electronic starter that is responsible for the release, you can leave a little more accelerated so that it does not stop but I recommend that you perform a visual inspection of the empty hoses that reach the carburetor if they are fine, do you have a maintenance to the carburetor and if you do not work you check the current part of the vehicle, do you have a mechanical pump of the vehicle, do you have the vehicle pump or electric pump?
