I have been trying off and on to get my TH350 dialed in for the last few months. I used this thread for reference many times until I was comfortable with the process. I appreciate the info you provided.

Mine was shifting at 4,000 exactly. I trimmed a little then I trimmed alot and got to 4800. Then I decided to take one spring out. Dont do that lol. I trimmed even more and it is right at 5,000. I am thinking about tapering the tip and drilling a few holes to get around 5200/5400

It really isnt fun getting that cover off and back on
