MG Midget and Sprite Technical - 1275 emissions 'de-tox'
|my big project this weekend was to remove the emissions controls from my midget (1973, 1275), since their value and function is somewhat questionable at best, and I am lucky enough to live in a state that doesn't test emissions on vehicles older than 25 years. I followed the instructions in Lindsay Porter's book, which refers to this as "de-toxing" the engine. I took many photos which you can see here: http://picasaweb.google.com/106239394014885586182/73MidgetDeTox1275# to document the process, maybe it will be helpful to others. And this way I have something to jog my memory if i should have to re-instate the system someday. i took a drive without the junk and found throttle response slightly improved. I only did a quick carb adjustment, i think i may still have the mixture a bit on the rich side. Next weekend I willdo a full tune of the carbs. Anyway, i hope someone finds this documentation useful!|

|At least it will make the engine easier to work on. :)|
|Too right, Carl. I had no idea there was so much space around the engine!|
Be sure to readjust your mixture and read the plugs to see if you might need different carb needles.
|Tempting as that might be, I think our State Safety Inspections in Missouri may include a look to see if all the original emissions stuff is still in place, even though they don't actually check for emissions readings. Texas may be different in that regard.|
|Texas vehicles over 25 years old are checked for "Safety Only" Brakes, lights, Horn, seatbelts.|
