hi brand newbie here,help think it fuel prob?
 

i bought this '84 cb650sc nighthawk put in new valves ,didnt relly need em but i had em,
heres the problem even before putting in the valves,
when i got it the #1cylinder exhaust would not get hot ,got spark,
now upon reassembly it spit gas out the exhaust,so off with the carbs for a major cleaning,
now it starts but the #1&2 cylinders just do not fire right unless i spray starting fluid in em then zoom,ok
it also will ALSO run right or fire if i hold my hand on the intake and block off 90% of the air going into the carb??
WHAT COULD I LOOK FOR and why one side i did replace the o rings on the fuel rail,
HELP, as i said i am new any help is much appreciated,THANKS,
