show us some pics

i might be able to help

sound's like the red lever is for the reserve oil (when engine oil resivoir gets low buzzer goes off and engine missfires) push that lever and provides enough oil to get you home hope this helps but without pic's im unsure?

you can see the red lever in the centre of the picture, and the fuel line going to the white elbow fitting and the other hose going to the VRO pump.

The red lever is the choke overide if you lose power to the choke twist the lever left or right and it activated the choke

you can check it by priming the fuel system up and when you twist it you will here the fuel releasing from the valve

Your fuel line goes the the stainer (fuel filter) and the oil line goes the VRO

Thanks Drew74,

That vacuum line sitting up in the top left corner. Does it go into anything or does it sit in the airbox?

It is a recirculation line it just sits in the top of the air box and there should be one down the bottom of the air box

If the red lever is actuated and the choke is on, then no 1 the engine would run rough and the vro system would overoil, would it not?

Yer motor mate the motor will rough for sure, more chance it will over fuel rather than oil.

If the motor is overoiling while it is running you will more than likely have a air leak in the fuel line from the tank to the motor (vacum side_

best thing to do there is check all the fuel fittings

To all those that assisted me with this problem, thankyou very much. The engine now runs quite smoothly, smokes a bit but what do you expect from a 2 stroke.
