Had some problems with over heating so I pulled the T Stat to see if it was sticking. It was and the temp problem was solved, Problem is, it started running really rich, ( pig rich, almost ruined mt TR6's). Even started to run rough. It's a new cam with no tune so I thought that was normal. So I threw in my new 160 T Stat and, Predetor was right, again, it does run rich without the stat....

No tune, new 85mm throttle body, heads and a rex and it idles at 950rpm... Nice...
