I offset the engine for 2 degrees buy tack gluing the firewall and put the cowl on to check it. If it looks OK mark it, knock it out and epoxy back in. I used all of the tri stock in the kit and add some more of my own. I Do this with the nose up in the air and fuse tied to by saw horse or bench to locate the engine. That is about as far as I got with it. Weather going to be nice for a few days heading for the lake. Dan
