I am heading up to Road America on Friday and believe that my WUR is not holding up its end of the bargain with respect to enrichment on boost. I have seen some of the writeups on adding an adjustment screw and to be completely honest... I am just not overly confident about the drilling and such. Is there an easier and quicker (key word here) way increase the on boost enrichment?

Thanks in advance guys.

 

Quicker? Nope

 

You can tap the gold pem down...a little.

The tricky part is defining a little. You should (actually need) to measure your pressure drop before and after with a CIS pressure tester.

 

Search a post by me titled "Warm Up Regulator", rennlister FLYN930 can convert your WUR to adjustable.

 

Thanks... already sent him an email and waiting to hear back.
