Help Installing Door Jamb Kit Over Unlevel Floor
I am installing a new bifold door and jamb kit over an unlevel floor and I have a couple questions.
1. I'm having carpet installed and am doing this now without any carpet, so I planned to hold the jambs 3/8" off the floor to allow for the carpet to be tucked under properly. But after that, what should be the overall height of the jamb so the door fits propertly over the carper? I assume the height of the jamb should be slighty higher than a standard installation over solid flooring such as hardwood.
2. The floor is about 1/2-5/8 out of level over the 27" rough opening (24" bifold door to be installed). Is it as simple as constructing the jamb kit on the floor first, cutting the short side 1/2 ot 5/8 shorter than the long side and installing it that way but then level the top of the jamb first then the sides?
3. It's a solid pine 6-panel bifold. I assume then I install the hinge side on the low point so that it opens properly and then trim the bottom of the door the same.
I've installed 4 other bifolds but never over a floor that was unlevel. So any help is appreciated!

I wouldn't use a jamb kit for bifold doors. I would just attach the track to the top part of the frame and the pivot plates to the floor. The height is adjustable on each side.

Pulpo - If you don't use jambs are you using the RO framing to attach the door to?
Zonabb - If the RO header is level you can just measure both sides and remove the difference on one side jamb. If not, I would put the jambs into the RO and level the head jamb using shims on the low side. That will give you a measurement of how much you have to cut off from the long side jamb.
Be careful about how you trim the bottom of the bifold. The clearance will change as the door is opened.

DO you have sheetrock on the walls? I'm curious how you will cover the rough framing lumber and the esposed edges of the drywall. Are you planning on casing the opening?
The only bifolds I've installed are the semi cheapo doors from the local big box. The height on those is only adjustable on the pivot side. If the floor is unlevel parallel to the opening, trimming the bottom is often a compromise.
