Bobby- Not losing fluid, other than overheating.
Tim- Since this engine was recently rebuilt just prior to my purchasing it, I think the valves probably need to be adjusted... something I'm not sure I'm ready to tackle just yet. I think having it checked over by a good mechanic is probably a good idea at this point. I'm just trying to get as much feedback as I can so I don't look like a complete dumb*** when I bring it in. I do want to eventually do all the work myself though.
