Welcome to Reoville and congrats on a nice looking Grand and good looking coil you have there. Another Hoosier in the house WOOT WOOT A couple of tips for ya cut an inverted V in the bottom of the feed tube. It keeps it from sucking its self to the bottom of the juice bottle. I would apply Noalox to the top of the battery instead of the firing pin. It uses more Noalox but you'll never have problems filing your firing pin because you won't need to. We have many more tips but I'll save those for our other Reonauts.
