I am having problems with my front derailler (3x7) 1995 F400 Cannondale

I have a 1995 Cannondale F400. I recently wanted to change some of the old lower end components. I was having trouble finding nice deraillers for 3x7 systems so I bought this one Shimano XT M771 Conventional 9sp Front Mech | Chain Reaction Cycles. The description says for 3x9 systems. When mounted low the derailler cage rubs against my second chain ring. When mounted high I get chain rub in most gears. I am having a lot of trouble adjusting this properly. The high screw does not seem to do anything. Is this the right derailler for my bike?

"Designed with Mega9 compatibility for narrow 9-speed chains"
You have a wider 7speed chain, possible issue.

Sheldon says 7-10 speed FD all compatible

I'd check for some youtube videos.

A 9-speed chain will work but the shifting on your cassette might not be as smoothe as it is with the 7-speed.

9 speed chain will not like his cassette, rear mech, or chainrings.

Op- stick with a 7 or 8 speed front mech unless you want to update your entire drivetrain.
