NOPE...it works and sounds perfect when I hold the handle down! Now what?
Good. Now you can optimize your flush. You need to adjust the flapper so it stays open for as long as possible. (Don't just adjust the number, adjust the actual chain, as well.) If that doesn't work, you'll need to adjust the fill valve so it lets more water in the tank. Raise it right up to the overflow tube (but not above it, of course).
If that doesn't work, you'll have to replace the fluidmaster flapper with a Korky. They also make flappers with little styrofoam balls attached so you can adjust how long the flapper stays open.
PS: is this the "kit" you installed? If it is, there may be other adjustments you can make.
"If it is necessary to increase timing for a longer flush, clip off plug from under
“Timing Cup” and push into any one of four holes in the bottom of the Cup.
Repeat for remaining two plugs if a longer flush is needed."
