Just put up a couple of posts praising the JD kit for my '03. Ran great on my test ride but did no low speed stuff. Yesterday I found my low end hesitation is not gone. Tunned with my Zip Ty screw almost the whole ride to no avail, rich and lean did not cure. Even unplugged my TPS with no change. Setup is as follows as per JD instructions: 170main 45pilot Blue needle on 3rd and I used the thick o-ring. Temps here are 80-55 and altitude is 0-500 feet. Any suggestion are appreciated.
