Neil,

Wow, thanks for posting the resistance values. That was MOST appreciated. I have not had the time to compare mine, but plan to and will post my results.

Your zero position setting sound right. Especially if its starting well when hot. Some incorrectly set the resting height a bit lower to cure stuborn cold start problems. But this usually results in problems with hot starts as the slightest pressure on the control plunger causes the fuel pressure to bleed off. The manual states that there should be slight free play ( the 0 - 2mm you mentioned) of the sensor plate before resistence is felt

One other question for you. When you set your duty cycle, did leaning the mixture (a counter clockwise adjustment at the mixture hex) result in a lower or higher duty cycle reading?

Thanks,

Tinker
