A-790 Control 72 Red Knob
Amazing quick delivery
Looks good
Very well made and Teflon lined so the operation is very smooth. A very large-diameter wire so it does not necessarily fit where the old one came out, but easy modification made it work perfectly.
Because of limited space between the firewall and the carburetor mixture control I had to go with this cable. The usual swivel 2-piece end from the regular vernier control was too long and didnt have enough space in front of the firewall to mount the adel clamp! This control works in that tight situation. Just silver brazed the wire end into a drilled out SS 10-32 screw section. One warning, because of the stiffness of the solid wire and wound spring sheath the bend radii have to be large!
Inner solid wire broke at 1500 Hrs.. ^(
Liked the way it looked when i ordered it and needed something heavy duty but this was not it , recieved the item and the inner cable was broken right out of the box.Now i have to reorder something else.
