RE: 1/2A Combat engine ?
Check out the kittining it together website. No engines or kits but he still has Galbreth heads, Nelson plugs and fine thread 1\2 A needle assemblies. These are a must with pressure. He also has the aluminum mounts that you need. They are already tapped for 2-56 bolts. Very handy. Get a Gladiator and strap that puppy on, add some nose weight and hold on! Oh, put a small prop on it to get it revin'.
