    Thanks for your reply, I went to the Dirtbike show today and bought an electronic stator which will hopefully do away with points and condenser.

    Many thanks I’ll check the carb, I’ve tried several new plugs.

    Hi, can anyone shed light on my question? Ive an Ossa 250 MAR 1976 model, I’m having trouble with starting it, it was running ok then died, on kicking over the spark looked weak, suspecting electrical failure I tested HT coil which seams ok, I stripped down and removed the stator. I’ve tested this and seams ok no open circuits. I am wondering, as the ignition is supposed to be Electronic, why are there points and a condenser fitted to the stator? Please can you help, I’ve posted a picture of the stator. regards Steve G

    Hi just joined so you are probably fed up with the usual requests. I’ve just bought a n Ossa 250 MAR, I need basic information as there’s no manual for it. I would be grateful of any information you can provide 1 ). Petrol to 2 stroke oil ratio. 2). Gearbox oil quantity 3) spark plug and points gaps 4). What should the compression ratio be . Many thanks Steve G.
