    Default Pop off piston stuck in pump

    Anyone ever had pop off piston hang up ? Mine has worked flawless for 2 years. Now it's stuck. I took bowl & impeller off & disassembled the valve itself , but the piston is hung up. I wacked it pretty good with a piece of hickory & sledge hammer but it aint gonna budge. Gonna try and make a puller tomorrow. Don't know what else to do ?
    ......................Why is It so hard to type on here ? Happens every time I get on PB , anwere else is fne......see !

    There must be something that got in there with it to hang it up. I have seen a hair make it between the float needle and seat in a carb. And cause it to sieze.

    Can you apply heat to it and then hit it?

    Yes , mine has a black neoprene type so I assume its the delron piston. Taking my outboard to the lake, I'll try & take a pic of popoff when I get back....Thanks

    Wonder if the delron piston can handle much heat applied ? Still planning on making plate for a puller but worried it'll pull threads out of center off the piston.

    I would put some penetrant around the edge and let it soak. Make a flat plate that you can bolt to the top of the piston with the 2 bolts holes already there and attach a slide hammer.

    What caused it to stick?
