Ruggles Rebuilt Running Rich In Start Up

<< < (3/4) > >>

Cliff Ruggles:
There is an adjustment screw on the front pull-off so that one is very easy to adjust.

Some rear pull-offs also have an adjustment screw if they are the double acting variety and control both functions.  You still may find yourself bending the linkage on them as they also control the secondary air door.....Cliff

steve s.:
Thanks Cliff.  Can you explain how exactly it gets adjusted?  Not sure which way it gets turned and what result I should be looking for.
Thanks.
Steve

Cliff Ruggles:
Turning the P/O adjustment screw clockwise will richen it up (not open as far), CCW will lean it up as it will open further.

It needs to be adjusted on a cold start-up, and you can fine tune the fast idle speed screw as well for your liking.  The speed screw is on the end of the throttle shaft under the choke housing......Cliff

steve s.:
O.K. Cliff, got it.  Thanks for the help!

Steve

steve s.:
Still having an issue with rich starts and getting the high idle to kick down.  This carb has two pulloffs, front and rear.  Should the rear pull off be hooked to vacuum too?  I was told to just cap off the rear pull off.  Is this correct?
Thanks again for your help.
