Hi Guys, I am installing a DLE 55 on my Areoworks YAK and am installing the ignition. Question is the plug boot does not want to go on all the way. This is my first gasser. Does the top cap of the spark plug un-screw off so it will seat in the boot or am I just not pushing it hard enough? The hole inside of the silicone of the boot seems way smaller than the top cap of the plug. HELP!! I am ready to get this baby running, but don't want to screw anything up. Any advise is appreciated. Butch.
