Title: California choke
Post by: 80strashlover on March 02, 2018, 05:14:38 PM

Newb on this site here. Question: I have a '78 chevy G20 sportvan that was made for California (I am in Colorado) my q-jet has a factory set, non-adjustable choke. Anyone out there have any experience with making these things adjustable? This choke is a real pain in the winter!!

By non-adjustable, do you mean it has rivets instead of screws holding it to the housing ?  If so, those rivets can easily be removed and replaced by screws.  Or it's something entirely different that I've never seen.  Hopefully, someone more familiar with a California emissions carb can chime in.

   What actually makes the choke a pain ?  It doesn't stay on long enough ?  Maybe you idle calibration is way too lean to start with ?  Maybe the idle tubes are partially clogged ? 

   Welcome to the forum by the way. 
 
  Don't forget to include your carb number in the next post.  It's stamped vertically on the driver's side, probably look like: 17058xxx

Very easy to make them adjustable.

I would test the choke coil to make sure it works, many will not.

Also check the pull-off to make sure it hold vacuum, many will not.

While the E-choke is off being tested it is very easy to make it fully adjustable, we stock the self tapping screws to replace the rivets, and on some housings you will need to take a small punch and remove the "stop" as well.....Cliff
