Hello, I have a 1986 Suzuki SJ410, which has not run for 5 years. He does start as long as he is cold (with drawn choke, without does not do much). However, if he gets warm, he takes almost no more gas, i.e., he goes out, is restarted and runs round or not at all. At first he did this only on gradients. But now actually immediately. I have already changed carburettor (starts better, but is also everything), air filter is new. Try to replace the petrol pump now Does anyone have any idea what might be the cause, or what else needs to be checked?
