Water Outlets: Check to see if there are clogged water outlets in the bowl. Mineral buildup can clog these small holes, and it's especially common in homes with hard water. Use vinegar and a stiff brush to break up the mineral deposits. Try flushing it again when they're clean.

It is quite common for minerals such as calcium and lime, along with debris particles such as rust to build up in the rim feed and jet holes of the toilet bowl. Over time, these deposits restrict and block water from flowing into the toilet bowl which will cause a weak or incomplete flush.
After you've poured the vinegar into your toilet, leave it to work its magic for 3-4 hours. If your limescale is particularly bad you can leave it overnight.
Unclog the rim
If these holes are clogged up with mineral deposits or other contents, then the water won't have the force to perform a proper flush. Using a bristled brush and toilet cleaner, scrub the rim of the bowl, especially the holes underneath the rim.
The most common causes for a slow-draining toilet are: A clog in the drain line. A blockage between the tank and bowl. Poor or Clogged Venting.
Causes for a Gurgling Toilet
Toilets can gurgle or bubble when there is negative air pressure in the drain pipes. The negative air pressure can create an air vacuum or air block. When you flush the toilet, this air has to go somewhere, so it comes up the drain pipe and is released in the toilet.
Heat 1 to 1 ½ cups of white vinegar to about the same temperature you'd take your coffee – not scalding, but warm enough. Add it to the overflow tube and give it about 30 minutes to work. Flush, then go to work on the jet holes, chipping away the scale with something small but solid.
