Tracy,

Could you please elaborate a little about some of the symptoms = that you have heard or know about that this will cure?  My Renesis starts = fine, but I get some rough running at speed.  I have had backfire once.  = Also, when I advance the throttle, the engine does a large hesitation before = it takes off in a quick rev.  Like a car might if it didn’t have an accelerator pump.

My air/fuel indication seems to be unstable also at speed.  = Is that related?

 

I put the circuit together this afternoon and will install it, = but I am wondering what symptoms I might expect to go = away… 

 

Thanks,
