Just for the record - I reviewed the EVO TPS a few years ago and mine would not run right. I called the manufacturer and was told that several of them got through QA with the wrong low-end needle setting.

The PROPER low-end setting should be as follows:


Remove the blue collar from the low-end adjustment.

Open the carb 1mm

Close the low-end needle

Open the low-end needle 1 1/5 (one and one fifth) turns

Replace the collar.
