So I'm rebuilding a WT carb from a Stihl 011AVT. From reading here, set the valve/arm height to .065.
Using the arm that was already in the saw, which knowing my Dad, it was never rebuilt, is a stock arm. Its less than .065.
I need to look again, but I think its set around .060 just with the arm at current height. Maybe between 055 and .060, I dont recall now.
As an amateur machinist with a full machine shop, I got to looking at the play on the arm in a 10x optical comparator as it lifts the valve, and theres a bunch of slop between the pin/arm/and metering valve (where arm engages valve) itself.
I can adjust to the required height, but theres so much slop in all that, it doesnt make sense for it to be between .065-.075 when there so much slop.
I didnt measure, but theres gotta easily be .005-.010 in slop, and thats probably being generous.
Thoughts?
