Hi Adzza, and a warm welcome to the forum. Could you please post pics of your machine, from different angles, so we may help you with the identification of your engine and model of slasher. The block numbers don't help much without a photo to confirm. Once again Adzza, to the forum.
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
