Blew engine on 96 f3. Bought 93 f2 as replacement. All hardware is off my original. Carb stator everything. My bike ran a month ago. Now this engine won't start but gets spark and cranks. Kind of like it isn't getting fuel. Not sure if all hoses are tight can someone pls help

 

With such limited information - I doubt anyone can help you, but if it ran once it should run again.
Check it's getting fuel - that's the most obvious thing to look for. Does it have fuel it in? Is fuel reaching the carbs?

 

Pump and filter good. I can blow into an air hose and gas comes out. I have two lines I don't know where go. I can send pic. Ones really long with some kind of brass fitting in center

 

where do these mystery lines start? How did they become unplugged? Did the bike previously run with them unplugged?

What help are you looking for here (if any?)
