Have you fitted the cistern high enough to get a good flow , older style cisterns needed to be a certain height from floor
Welcome to the forum. Although you can post in any forum, the USA forum is here in case of local regs or laws
You didn't say it flushed properly with a bucket, just that a bucket was needed to finish the job. What happens if you pour a bucket down it wthout cistern flushing first and do so at roughly the same rate as normal flushing rather than slinging it down there?
If it clears then it sounds like the problem is prior to the pan, if not then it could be the pan and/or after the pan

Ok, thanks for all the replies.... To clarify...
1. You do need to sling the water down, normal pouring rate is not that successful.
2. The pan is clear and so was the pipe in the floor as far as I could tell.
3. The actual vent pipe which serves the main drainage, ie the kitchen and upstairs bathroom is further along the house. There is a manhole in between which is cemented over with a patio slab, however this was also clear a couple of years ago. There is also a manhole in the garage floor which is on the main run out and we used to have problems with it stinking. It has a carpet over it now so I have no idea if it still stinks!
From what you are all saying, should I be thinking that maybe it's more of a flow problem than a flush problem, ie the waste isn't able to draw away effectively? How can I check if the vent stack is doing its job?

my advice would be retrieve the old syphon and get a washer for it or make one from a suitable thickness of rubish sack
That's long gone unfortunately..... as the problem was pre existing I slung it out...
Or wouldn't a drop valve be worth a go? Surely a Fluidmaster has to be able to empty a cistern with as much oomph?
I think I'll try that idea... Got to be the simplest thing to try first, thanks!
