It is.... it's still hard to start.... when it's cooled a bit, I have to work the throttle to keep it going as it starts... when the wideband heats up, it grabs it and keeps it going - although it does hunt some.... between ~ 14.0-15.5 AFR.

Are the coolant hoses that feed the Mitsu IAC only there to control the wax element? If so, it would be nice to get rid of the hoses.

One thing I see I like about this engine already.... manifold vacuum is 16 in/Hg at no-load 2200 rpms! <img src="/forums/images/graemlins/scared.gif" alt="" /> I only had 18 in/Hg at 650 rpms on the last engine.

Larry - two of the bolts may not have been brass - it could have just been a wash coating on steel, but they sure looked like brass at a glance.
