I'm building a Tutor 40 (first ever model) and have an OS 46LA engine. The prefitted mount is allegedly suitable for this engine according to the instructions. Problem is that the holes in the engine do not match the holes in the mount arms. The Irvine instructions appear to suggest that the two metal brackets they supply just sit on top of the engine flange and hold it in place by friction/force (the bolts going through these brackets directly into the mounting arms.
Is this correct or should the bolts be going through the holes in the engine and then into the mount arms (in which case I need to have a different mount - the other one supplied by Irvine doesn't fit either, even though it does have recesses in the mount arms that would help keep the engine stable). The OS instructions clearly show the holes in the flange being used to secure the engine in place ????
