Good old 10287 had a pretty good 2017. The only issues that have cropped up and I haven't been able to resolve is an occasional hesitation to accelerate when cold, and then disappears once the engine is up to operating temperature and feeling a slight miss at idle. It's very mild but it's persistently there all the time. After doing some reading and research here and other places with K-Jet data I am leaning towards the CPR/WUR needing attention (after all it's a Warm Up Regulator and that's where I had the most noticeable symptom). Does this sound like what I think it is? And what's the remedy for CPR/WURs? Send it to be rebuilt or traded for another rebuilt unit? I usually use PJ Grady or DMCMW. Thank you all and Happy 2018
