    well patience does bring joy !

    it loosened up after 4-5 weeks of soaking the rings, gentle wacks on the pistons , openning it’s fuel ports and blasting in some engine fogging oรฏl
    and…. waiting

    I can now turn the flywheel with one hand, no screeching pistons are sliding in and out like a swiss Watch !! ๐Ÿ˜€

    I will close it up and regasket the head.

    any sealant needed here as I am using a Sierra headgasket ? I had asked for OEM gasket but clerk ordered me a Sierra ๐Ÿ™

    I will change the impeller and try it out before messing with the funny carb. ๐Ÿ˜•

    Just because it’s spinning doesn’t mean she’s ready to start!
    My 12D10 was frozen, I got her moving and moving quietly. On the recommendations of some of the members here I pulled her apart and checked the rings. 4 of the 6 rings total were stuck in some form or another.

    I am not to experienced on that level of surgery so I can only run some engine cleaners or seafoam like mixes for now and hope for the best .
    I’ll check points / iginition etc… the usual easy things

    If you can remove any of the ports so that you can see into the cylinder, you can check the rings with a little screwdriver. You can push them, if they move they’re free and you’re (probably) good.

    It’s not that hard to take them apart and get them back together after. You just need to keep track of the parts. There’s enough information here to help you out if you get stuck

    I will consider it but this engine is "like new" and I just don’t want start inspecting exhaust ports behind the exhaust baffle or pulling the carb and reeds

    I’ll chance it for now with a good dose of engine tuners

    thanks for comments …btw should I dab the headgasket with sealant ?

    I don’t pull them apart until I have exhausted all
    other options. The rings are seated in the cylinder
    and if they are not pined they cant be put back in
    their original position which results in some
    compression loss. If the motor is in good condition,
    and the outward cosmetic appearance indicates it may
    be, if the rings are only stuck you’ll have the best result
    if you can get them freed up without disturbing them.
    In a tank or on a boat, using Sea Foam and 5 oz. of oil
    per gal. you need to see if you can get it started. If it
    starts you will want to let it run about 5 min.
    Then shut it off and let it cool. Then repeat. As the rings
    and pistons heat up they expand. When they cool they
    contract. This movement along with the detergent in
    today’s oil and the Sea Foam will free them up over time.
    When the compression comes up enough it will push
    the boat just use it. As the motor cleans out you should
    notice improvement in how it starts and runs. If it wont
    start let it sit for a few more days and try again. If you
    cant get it started at some point it will have to come
    apart.

    Did you ever post a picture of this pristine motor? I looked back over your posts and don’t see one.

    quote Mr. Asa:

    The 9.5HP motors like this don’t have the traditional port/exhaust covers, so not easy to look inside.

    I woud do a quick compression check, and give it a go! Run it a bit and check compression again.

    No, there is no sealer used on the head gasket.
