Hello all. I posted this over on HTT also but I am curious to any information or advice the gurus on here will have. I'm working on a rarely ridden 1990 883XLH that had fuel dumping out of the overflow tube and air cleaner when not running and the petcock was in the on position. I cleaned it and installed a rebuild kit but the problem continued. I found the problem was the needle valve seat was filthy. After I cleaned and polished the seat, the valve held fuel. The problem is I'm not sure exactly how the float height should be set on this model. The float style is the earlier twin white plastic barrels not the black float on the later models. I've read many conflicting measurements and procedures. Some say take the measurement with the carb at a 15-20 angle, and some say take the measurement with it flat. I like the idea of checking it with a clear hose on the drain line but have read conflicting info on that procedure as well...some say take it with the bike running and some say not. Most of what I've read says the level in the hose should be even with the bowl gasket surface but I would like to hear any opinions on that. So to make a short story long, my question(s) are:
1. If I use the conventional method to set the float what is the correct float height for this model and should the measurement be taken flat or at a 15-20 degree angle?
2. If I want to use the clear hose on the bowl drain method to measure float height should the bike be running or not, and exactly where in relation to the float bowl gasket surface should the fuel be in the clear hose?
I've read till my eyes are bleeding and haven't found definitive answers yet that are agreed upon. Any advice, info, or opinions will be much appreciated. Thanks!

Your official Harley service manual will tell you all you need to know.

Since I don't have mine handy, I can't help with any more than that.

Unfortunately, the owner lost the manual and some say that year manual has two different values and/or a misprint about the correct float height. There are a lot of different opinions and answers on the subject...just curious to see what others have experienced.
