    Got a couple of old Echos that I'm trying to get running again. One is a SRM-3000 trimmer and the other is a PB-1000 blower; they have been in storage for years. Zama carbs; one K26 and one K21.
    I replaced the cracked primer bulbs and fuel lines and filters, cleaned carbs and installed kits.
    Same problem with both carbs: not priming hardly at all.
    Squeeze the primer bulb and gas comes up the line but not really into the bulb.
    Tried swapping lines, replaced screen filters, checked for fuel line kinks, etc.
    I messed something up but I can't find it.

    Sounds like you have the diaphrams and gaskets installed wrong.....
