1982 Honda magna 750 wont start ?

I just got this bike from my buddy, its been sitting for a few years in a barn,the guy who owned it had taken the slave clutch apart at some point and i guess he got sick and died,i have the bike now and i put the slave back together ,the piston was frozen and i cleaned it up and put a new gasket, the spring seemed strong,and put the slave back together and on the bike,i tried to bleed the clutch line and fluid wouldn't come out of the bleeder valve at the slave ,i disconnected the banjo bolt at the slave and looked to see if fluid would pump out and it wouldn't,i disconnected the line at the master cylinder and pumped the clutch and Fluid didn't come out,im going to get a rebuild kit for the master cylinder in the morning ,i try to start the bike and it turns over but doesn't start,i wonder does the clutch not working stop the bike from starting? i put a newly charged battery in it but i did notice that when i tried to start it the bike would turn over while the engine kill switch was in the off position....any ideas would be a great help thanks......
