control pressure regulator and vacuum connections 200 1982

posted by  someone claiming to be bbben on  Mon Jul 29 14:16 CST 2002 [RELATED]

The car is a 1982 Canadian B23E with K-jet. Have been tooling around looking for the cause of a crappy idle when the engine is in its 'still cold but almost at running temp' stage. I noticed the thermostat valve did not have any lines to it, nor did the control pressure regulator seem to have any vacuum connections at all. Being a Canadian car (Edmonton- its COLD in the winter)I imagined it would have the full cold enrichment system, but does not. Starting the car in the cold is never a problem. When it is really cold (-30c) the car starts fine, then idles high for awhile- as it is supposed to do- and then stalls at idle for a few minutes of around town driving, and after that goes to a very high idle, finally settling down to normal after that.
Anyway, is my CPR the wrong one? Do more recent ones (can't quite make out the part #) not require vacuum? This is a mystery I would like to solve.
Thanks.
