I installed the new battery and it cranks like a banshee. Compression is 154 and 157, I have spark but it still won't fire and stay running. I double checked valve adjustment it was still good. If I mist some starter fluid it will run briefly. Very briefly. I have tried switching coil leads and have established that they are where i want them, as the bike won't even sputter the other way. I am guessing that my problem is carburetor related so it looks like I start all over again with those...does this sound like a reasonable assumption to others? I am dying to ride this thing! HELP!!!
