"Start with the basics - compr

"Start with the basics - compression check and spark check to rule out a blown cylinder(s) or an ignition problem.

If both are ok then concentrate on the fuel system (which is most often the culprit). Start inside the tank - gas pickup, tank vent(s), air leaks in the fuel line between tank and motor, any filters "in-line" or under the hood, fuel pumps (both high and low pressure), water/vapour separators, injectors and fuel pressure regulator - not sure if the fuel rails on this model have a tracker valve or not - if so, check that as well along with any/all seals/gaskets.

You have an injected model that resembles your cars motor much more than a conventional 2 stroke - you don't simply adjust a screw on the carb and hope to make her run smooth.

So either get yourself a manual and dig in or take it in and have it looked at - you can chase your tail for a long time trying to track down a problem when the culprit could be one of 2 or 3 dozen bad components..."
