Mount the engine mount, then the engine, then the cowl. After you have the engine mounted in the mount on the firewall measure the distance between the firewall and the drive washer on the the engine. Now tape the cowl in place on the front end of the plane. Set the cowl in place so the the front of the cowl where the engine shaft comes out is 1/8th of and inch closer to the firewall then the drive washer. Follow me? This should give you enought clearance for the right thrust. Do not line your cowl up with the right thrust of the engine, it will not look right. You may have to take the engine out of the plane to mount the cowl if the engine doesn't fit in the cowl.

Now after you have the cowl taped on the front end drill 3 holes on each side of the cowl threw the cowl and the plane. Take the cowl off the plane and drill the holes out ON THE PLANE large enought to fit some yellow nyrod in the holes. CA the yellow nyrod into the holes on the plane. This will give you something good to screw into instead of screwing into wood.

Get your cowl and put some rubber gromets into the holes. This is a good method to vibration mount your cowl. Esp if it is a plastic cowl.

Now put your cowl back onto the front end of the plane and secure the the cowl to the plane with some #2 button head screws. There you go!!!! a nice vibration mount cowl setup!!!!
