1350.11Pots OKCHEFS::GERRYTTue Feb 25 1997 09:1911
    Well, I took the heads off the pots and they are fine. Pistons look
    clean too.
    
    The seizure I believe is caused by the kick-start/gear change mechanism
    on the engine (JAWA 638). The kickstart won't depress. The gear
    selector was working ok.
    Has anyone any ideas how this can be fixed?
    
    Cheers,

1350.12Sounds seized to meFOUNDR::DODIERDouble Income, Clan'o KidsFri Feb 28 1997 11:0513
    	If the engine is seized, the kick starter won't move either. Reading
    a few back, you can use either Liquid Wrench or Marvel Mystery oil and
    pour it into each cylinder. Let it sit a night or two, then try to move
    each piston using a hammer to strike a piece of wood (1x1) on the top
    of the piston.
    	
    	If the engine has been setting for some time, the piston is usually 
    what seizes. You're only trying to break it free, so start with little
    taps, and if it moves the slightest bit, switch to the other piston. If
    you get them both free, then try the kick starter. I have done this 
    successfully on 2 and 4-strokes without damage. Perhaps I was lucky. 
    
    	Good luck.....Ray
1350.13Split enzCHEFS::GERRYTFri Feb 28 1997 13:178
    Well, if it has seized, then it's at the bottom end...cos the cylinder
    barrells come off fine!
    
    Maybe I'll just have to split the engine!

1350.14Well, that's not it ;-)FOUNDR::DODIERDouble Income, Clan'o KidsFri Feb 28 1997 15:194
    	Yep, it's definitely not that if the cylinders come off ;-) Evidently, 
    the connecting rods and crank look fine, of what you can see of them ?

    Hello Ray,
    
    Yes, the rods all look fine.......I'm pretty sure its the
    kickstart/gearchange problem, but as I haven't a garage to work in it's
    a problem during these dark evenings....I hope to look further after
    Easter
