Sounds like your slave and/or clutch master cylinder are shot.....easy to replace and not expensive at all when you buy them at your local parts stores or even better, RockAuto.
Don't "bench bleed" the clutch MC, just install it and then bleed it with the bleeder on the slave cylinder.
I think the #1 spark plug tower on the dist. cap needs to be at the 9:00 o-clock position.......also, that rotor can go on in 3 different positions (triangular post it fits on!) so you need to make sure the dist. is installed correctly for this to work exactly right.......I'll see what I can dig up on instructions for this.
Meanwhile, here is a couple of pics of the cap and plug wires on the B2600i I just put together....
You line up these 2 marks on the dist. before you install it while holding the dist. housing in the exact position it should be in when it's fully inserted. The rotor should spin a little as the cam gear and dist. gear mesh together.......and remember, the motor should be at TDC (HB timing mark on the zero of the timing scale while on the compression stroke for #1 cyl.) when installing the dist.
