Like others have previously posted: the "put put put to life" is typically a symptom of high control pressure under the "cold" phase of the WUR. If this is what you have, then you'll need to adjust that...

Our host has the gauges: TOL-TA33865 for $99

I had BL send me a programmable WUR [I think I had to give him the part number off of mine so he could match it] and I simply mailed him mine once I got his installed.

I wouldn't know the first thing about rebuilding a WUR, myself... So, can't help you there...

Because I have a wideband AFR, I enjoy instantly seeing the results of my adjustments [either: cold, warm, or enrichment].

Because this is my first year with the 930, I noticed that as the weather cooled off [90's to 60's], I had to lower my cold control pressure setting to get a smooth warm up [from 60-F].
