Try this for a few flushes and see if you still have the problem.
When you flush, hold the handle down. This will keep the flush valve (flapper) open until all the water in the tank goes into the bowl. The bowl should start to fill, flush out, then refill, and probably flush through again. The extent of refill and the following secondary flush will depend in part on how much water is in the tank.
Be careful when you do this. If the problem is a partial blockage in the bowl trap, you could wind out overflowing the bowl and have water all over. If the bowl begins to overfill, and before it overflows, (make sure you have already removed the tank top) release the flush handle – you may need to reach in and make sure the flapper closes.
If this gives a good flush, the rim holes may be clogged and may need cleaning, this is one reason that the proper amount of water no longer drains into the bowl when flushed, causing an incomplete flush. There are also other causes.
