[urq] WOT enrichment

[koenigj at comcast.net]

Can't claim a lot of BTDT, but I've always been intrigued by the fact that the WOT enrichment essentially comes from the WOT switch establishing a fixed duty cycle.  In order for this to work as intended, the 'normal' range of duty cycle (proper mixture adjustment) would have to be operating such that the WOT fixed duty cycle produces the desired  difference rather than, fo example, switch to a fixed duty cycle that leans the mixture . 



Perhaps you made some pressure tests and mixture adjustments with the new WUR ? 



Am I all wet?

I had my engine pulled a bit ago so I could freshen up the engine bay.  81 WR.  After reinstall I was not getting full throttle enrichment as measured by my ear and AF meter.  Having just found some of the proper banjo bolt washers, I just got my rebuilt WUR back in.  The response is much better across the spectrum but I'm still not getting full enrichment.  WOT switch is working, WUR is getting 12V, N75? Valve working so I am at a loss.  I was thinking electrical miscue with the engine in and out but now no idea. 
Also what fuel pump are folks using who still run a stock 10V? 
Thx 
Mike
