If you guys remember my previous post...fell flat after my first high speed run after the bbk ...started making a weird knocking noise! The guy that helped me put the bbk called and said he was wondering if a fouled plug could cause the prob. I took both plugs out tonight after checking the valve adjustments and it does seem like the front cylinder plug is barely firng kinda orangish... switched plugs and it moved with the plug. The other plug seems nice and white when it fires. Do you guys think this could be the problem? The backfiring makes me think it is something other than a rod or crank bearing! I have my old plugs ...Should I put the front rocker cover back on and plug and try it again? Some of you kinda got on me for starting it twice...may cause more damage, which I understand, but one more time, what do ya think? Thanks...Bent
