B25860 Special Tool for Stromberg 175 CD Carburetors - Slotted Head
Special Tool for tuning the Stromberg 175 CD carburetors.
Please note that this is the version with the "Slotted Head" end.
It locates into the piston assembly and allows you to rotate it.
Turning it clockwise raises the needle and enrichens the mixture; turning it counter-clockwise lowers it and consequently weakens the mixture.
Throughout the years, Stromberg (and consequently Zenith which are similar but in name) has used various ways of adjusting the mixture.
This version here uses the "raised blade" that you might also recognize as a "Slotted Head".
The other version is dubbed "Allen Key" by Stromberg and is basically a hexagonal head.
This latter version can be found HERE.
Either version is a vital tool for both the DIY mechanic as well as professionals!
