The Mexican Beetle doesn't come with any sort of thermostat and it's running pretty cold this time of year.  I think this is contributing to my idling problems.  I had to do another bottle of FI cleaner this week just so it would idle.  After I put it in I went out and ran it hard on the interstate and it smoothed out.  Even after that, the dipstick was just lukewarm.

  :angry1:
So, does anyone know any GOOD way (go ahead and submit the jokes about  stuffing a rag in the fan or removing tin if you like, too) to get the engine to hold in a little more heat?    :lookaround:

Running cold ?   Well that is a switch.

Next he'll be complaining his bug is not leaking oil.

I really don`t know what to say about this.  I never could tell a lot of difference with or without flaps or thermostats other than maybe the engine would warm up a little faster .I would think if you used a power pulley it would put a little more heat in the engine maybe , but I think it would also slow down the volumn of air/heat going into the car, but not by much. I wonder if there is any difference in the Mexican fans Vs U.S. or Euro fans ?  If your car has vents in the deck lid and under the window you could try blocking off the deck lid vents only. Bugs ran for years without deck lid vents before 1970, but without some kind of temp. gauge to moniter things ,I just don`t know. If it was my car , I would more than likley try it for a mile or so then check on it. If your heater starts working really good , you might be overheating the engine.  It would be nice to know what the oil temp. is running as you are now.
   Anthony, You are the first person to come up this problem that I can recall. :?

I ran across this interesting piece while searching the internet trying to find out the diameter of a stock pulley.
