Installation was easy, and was a quality product just as expected. It even came with a tag reminding me not to pull it out too far, which would be easy to do, because a small ball will fall out and it could be difficult to replace.

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!

Q: Can the sheath and cable be trimmed down in length if the old model falls between selectable sizes?

Q: Can the A-790 VERNIER CONTROL solid inner cable be removed from the outer casing so that the casing can be cut, or must the casing be cut with the inner cable in place?
