i download and was looking at the instructions on engine mounting and of course there are pictures using the g62 in the manual. i was just wondering if a piece of plywood is required not only to steady the g62 when mounting it but to push it forward a little so it will fit onto the cowl correctly? if a piece of plywood is required, how thick? in case this matters, i plan on buying the B&B specialties packing including the mount, muffler, spring starter, etc.
