[TR] TR6 Zenith Stromberg Carbs

[Henningsen, James D.]

Ok, it’s been a while since I’ve adjusted the mixture on my ZS 175 CD-2 carbs on my TR6.  I have the adjustable B1AF needles,  removed damper from carb body, removed the fixing screw from the piston damper side.  I insert the special tool into the damper tube to turn the needle assembly and it engages the hex socket hole.  I can rotate left and right but it doesn’t move the height of the needle face on the bottom of the damper no matter which way I turn.    If I pull the needle down from the damper to its lowest spring position and then turn left or right, the needle seat height does move up and down.   I don’t recall having to hold the needle out to adjust mixture.  I also can’t easily find the fully lean or rich stop points easily.  Ten turns seems a bit much.

Any thoughts greatly appreciated.  Trying to get my refreshed 6 back on the road from a major engine drivetrain upgrade. Thanks I advance
