[TR] TR6 Zenith Stromberg Carbs

[Jim Henningsen]

I finally got it to do the 3.5 turns.  I took out the needles and cleaned up everything.  Had some grunge in the screw area.  Turns out the little screw on the side of the piston damper needs to be in and set on the flat side of the needle seat.  With it in, the needle adjusts with the special tool.  With it out, it just spins and no adjustment happens.  Like I said, it’s been a while since I worked on the zenith carbs.  Good re learning experience.  Running much better now!  Thanks for everyone’s advice.

>>> 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.
