Hi luvpsi, in order to give you some advice, we need you to grab your camera and take some pics of the engine, from different angles; including the carby, and include any model and serial numbers you find for the engine. The pic of the brochure is way to small to see anything.
Please do not PM me asking for support. Please post your questions in the appropriate forums, as the replies it may receive may help all members, not just the individual member. Kindest Regards, Darryl
