it starts ok,runs ok for a few minutes then fades out of power till it stops.it wont restart for a few minutes then the same happens?this happened after (i think it did)ran out of fuel mixture.sincethis problem started the fuel tank is pressurised upon easing the filler cap open followed by a large airbubble when cap fully removed?

If it runs ok with the cap loose it has to be a tank breather issue creating a vacume in the tank

try taking plug out spray carb clean in then pull cord hard few times,putin a new plug in,empty the fuel tank esp the fuel filter,changing the fuel make sure correct mix of 2 stroke and all the filters.also adj screws mite need tweaking
