Base problem: Takes a couple of seconds for the RPM's to settle down to idle after I hit the throttle (@3500-4000) Rpm and then back to no throttle.
So, putting vacuum gauge on the small line coming from the step elbow that feeds the decel valve (again, the small line) I have at idle 10 hg. at 3500 I have 18. With the bare decel valve on my bench, I apply vacuum to the small end, and blowing into the side tube (that runs to the top of the air box) it takes almost 20Hg to just barely get the air to move out the other large end of the Dcel valve (Valve opening). It would appear to me that the decel valve is never functioning and hence my problem. I have used some cleaner to loosen it up but that's where she's at now. First off, do I have enough vacuum? If so how many HG should it take to open the valve and is that adjustable with that nut on the decel valve? Dave |
