Thanks for the info guys! <img src="/forums/images/graemlins/kewl.gif" alt="" />

Well looking at it last night it had threaded screw holes and what looked to be a functioning hole/port. I didn't see if it was drawing vacuum. I just sealed it up for now.

I did however re-time the motor back down 2-3? to stock. That seemed to have made a big improvement all around. Drives better and doesn't appear to be running near as rich.(My eyes aren't burning in the garage anymore! <img src="/forums/images/graemlins/lol.gif" alt="" /> )

Last question(s): Why would someone have the spark plug gap set at 0.041in? Is anyone else running that hot of a gap on a stock motor?
