How to adj WUR fuel pin adjust on CIS 930
Where is the fuel pin that controls what the control pressure drops to under boost on a CIS 930?
I've read about people modifying these things to make pressure drop lower, but I have no idea where it is... thx. |

The WUR makes the mixture richer under boost.
Here is an excellent modification for the CIS WUR. I did this to my 930 and it made setting the control pressures a piece of cake. Adjustable WUR Here's a shot of the WUR. The small nut is screwed in to raise the control pressure.
