TruenoGuy Posted December 29, 2013 Report Share Posted December 29, 2013 I'm replacing the stock carb with a Weber 32/36 and de-smogging it at the same time. I can't figure out what this line is for. It runs down to the transmission. Quote Link to comment
datzenmike Posted December 29, 2013 Report Share Posted December 29, 2013 The metal rube connects to the vacuum throttle valve on the transmission. It adjusts the up and down shift points relative to engine load signaled by intake vacuum. The other open end connects to a short rubber hose which either connects to a fitting on the rear half of the intake where the brake booster hose connects or sometimes to an inline fitting on the brake booster hose. Here is my '74 710. You can see the line coming up from the transmission near that yellow tape, around the throttle and down onto the intake at the brake booster hose fitting. Quote Link to comment
TruenoGuy Posted January 3, 2014 Author Report Share Posted January 3, 2014 Thanks Mike, the previous owner didn't have it hooked up. It shifts so much better now. Quote Link to comment
datzenmike Posted January 3, 2014 Report Share Posted January 3, 2014 I'll bet it does. 1 Quote Link to comment
