    Anything else?
    yep! the "sleeve" looking thing should be removed as it is stuck on the cam shaft itself. good thing these are a dime a dozen for parts! yours looks trashed.

    Even though the bottom end is full of clean oil without running periodically the head and piston have most certainly gone dry. Trailers are ok storage but I noticed in certain temperatures and conditions there can be condensation which doesn't go away easily. That will most certainly get in the motors. They probably are not destroyed at all but I bet you will have to open the top ends to get them cleaned up.

    Well, I did end up making a little progress yesterday

    At which point I remembered Dirtccrasher saying in another thread "Don't force it"; at which time I proceeded to get help from this board and forced it to get to this:

    The timing chain was very tight. I worry about being able to set the timing correctly if I ever get it all back together but I am sure I will.

    I took pictures of the valves but you can't really see anything. The intake valve is rusted-everything else looks fine.

    Slowly coming apart-Very little time to work on Sinatra:

    Rusty as a 42 Ford! So I cleaned it up a little and finally got the sleeve loose with alot of light tapping from a rubber mallet and the ultimate sin of driving a 2 inch paint scraper in between

    Never could get the piston unstuck so I left it soaking in a shot of mmo, a shot of acetone, a spray of pb blaster, a shot of atf and another shot of atf:

    It'll be a week before I can get back to it so what do I need to order? Rings? Piston and rings? Rings, piston and cylinder? Piston, rings and get my cylinder bored for $60?

    Thoughts on getting the piston unstuck?

    Appreciate all!! Hope I didn't miss anything.

    maybe pour out the liquid and hit the piston top around the rings with a propane torch? I'd just have it bored, ebay piston and ring kit is cheap enough. Get a valve job done at the same time and should be good for the next ten years. jim

    Going to try a little heat tomorrow. (thanks Jim)

    So I move to the 250sx of the RatPack (Dean Martin) and try my new valve adjuster (which didn't work because it wouldn't fit and I couldn't turn it with my hand)

    Don't buy these

    So, I sit on my US90 and decide to turn the valve adjuster with a pair of long needle nose and I loosened it up a couple of turns (because MrC of MrC's garage fame said he likes valves loose for initial start)

    A little starter fluid from the local Dollar General and boo-yah! First a pop, then a bust off and then a little run!! It was the preverbal good golf shot that I needed to keep me in the game.

    On the 200, maybe you could try lifting the cylinder as far as you can again and putting some wood blocks underneath it to hold it off of the case. Then try gently tapping the top of the piston to see if it will move down. Be sure to try to cover the opening in the case then best that you can.

    Thanks 350. Called myself trying that but it never broke free, probably "tapped" it harder than I should've.

    Great project, these are really making you work for it, I would still like to know the back story, how 1 guy ended up with 4 locked up machines (grenaded).
    I am glad you found something useful from my videos, I am doing 1 a week now.
    Hearing one bust off for the first time after you work on it is the closest thing to giving birth.
    ok, may be not, but you know what I mean, its a great feeling of accomplishment.
    Great job, keep digging

    Thanks MrC, but to be honest, Barnboy and myself are going to need another 3WW shoutout on one of your vids before we watch many more! JK

    So..Very good day today (and from what I mean by "day" is the hour or so that I get to work on the trikes)

    Dean Martin is starting and running on gas. Pretty cool; still needs carb cleaned and recheck compression before I buy tires

    I also got an 86 200x started that I have not talked about, but glad it's running-to some extent anyway: it's being sold tomorrow. Kinda hate to let it go but $$$$$

    And then with a few taps, a few pretty good hits and a little heat (per Jim Mac):

    I've only been into the rear drum brakes on a couple of trikes and am far from being an expert. Is there a circlip on the axle between the cover and the threads? It kind of looks like it. Warning:I may be wrong.

    99% sure it splined and the drum slides off after removing the 2 nuts. you can prop up the rear, put a wooden block on the threads and smack it toward the sprocket side. jim

    I should have said the axle will slip out to the left (as your sitting on the trike) when the drum clears the splines it slips off. jim
