[QUOTE="Tazza, post: 15981, member: 82"] All i can suggest is to replace your fuel filter. Run the machine and if it stops again look at the primer bulb, if its flat your have a blocked pickup filter inside the fuel tank. If you still have problems and those didn't do it, your problem could be the lift pump diaphragm has a split allowing air in. Also check that the bleed valve on the pump is fully closed. Just a few things to try. Is the smoke white or is it blue? It could be a bad injector, you can test them by pulling the injectors and attaching a fuel line to the pump and hang the injectors off it and spray down and cranking the engine, you can check the spray that way. Or you can get them checked at an injector shop. White is un-burnt fuel, blue is burning engine oil, black is excessive fuel. [/QUOTE]
