the title says it all, I had to run the motor without oil for a few miles, then engine froze (the chain didn't jam in the drive sprocket, the motor disengaged when I held the clutch in, but wouldn't move even when the spark splug was out and had no compression)
so i took the top off and had to push the piston down, this made it disenage when the spark plug was out and had no compression, bUt..I tightend the clutch screw 0on the right side and still the motor NOW does not engage. its like the exact opposit has occured. did i strip something when i forced the piston down? im just so upset because i already purchased a motor and that broke down and now this one, i have been into these motors for over a year now and have only been able to drive one for a couple weeks str8. theres always something going wrong..PLEASE HELP this is my only transpo to and from work..:(

it's clear you're desperate for help...all the more reason to wanna be nice to the guys & gals...while you're waiting for help (and hopefully read read read'ing the forums) how about you check in at "introduce yourself"...it's forum policy to give the group a heads up about why you'd like to join in :)

if you're just gonna get help and scoot, that's cool, too...but we still wanna know, m-kay?

your description is confusing (to me)...maybe someone can figure it out for you. i wouldn't dare subject my 2-stroke anything to a single revolution without oil, much less a few miles...anyone can clear that up is welcome to chime in.

ok..

i will introduce myself now,
im sorry if its so confusing, i think since i ran my motor with any oil for half a day it might have ruiend my motor, then when I pushed the piston down and unfroze it, my clutch seems all messed up, and no tightening it will help (on right side of clutch/gears) i have my old motor NOW..


what happend to my old motor was this, the housing on the left side CRACKED and the front mounting cracked too, long story, anyways is there a way i can switch the clutch or the"insides" from my old motor to my new and INTACT motor? thx ..

:cool:

based on the weird symptoms, i think you're gonna have to tear it down. if you're considering a swap-out of parts, you'll have to tear 'em both down to see what you have to work with.

we're gonna need some pics of everything if you can. just keep everything in this here topic until we get it fixed.

ok..

well, i dont have any way to take pictures, wish i did. is it possible to tear it down? is there any advice or step by step instrucions on how to?
PLUS i just put the top and spark plug back on after tightening the right side gear nut evn more, and it seems harder to move now..but my clutch arm is hitting the bottom of the carb so i dont even know if it will work this tight anyways. ahhh...if i do tighten the nut evn more on the right side, and make it engage, is there a way to adjust the clutch ARM to make it disengage therafter? thx

Don't take this the wrong way man and normally i wouldn't say this but u seem to be out of your depth.Do u have a friend or neighbour u can take it to,someone who has good mechanical ability.Professional mechanics are costly but u really need someone who will pull-down both your engines and show u how they work and how to fix them.
There are no step be step instructions because we don't accurately know the nature your problem/problems and without pics it makes it exceedingly difficult.
READ AS MUCH AS POSSIBLE HERE.Buy a cheap digital camera and get back to us.
I'm assuming u have a 2-stroke Happy Time but you've never said....u did say u ran it without oil so i'm further assuming u meant no oil in the fuel.
These scematics might help:

PS...this is where u get them from:

I agree with fetor56 on this. You should never run a 2stroke without the proper amount of oil mixed in the gas. NEVER!
These are quite simple motors but, you would still need some experience, or the ability to share with us more info, (pictures, vocabulary). Until then your best bet might just be to find someone close by who can offer their skills to help.

Sorry to hear about your divorce and bike problems. Been there done that. You mightfind a small independent motorcycle repair shop. The one down the street gets a kick out my Happy Times and have helped me out several times free of charge. In return i buy my oil and chainlube there.
Dittos to all thet Fetor said, I think they even make disposable digital cameras now.
Good Luck. We'll do all we can to help.

I agree with most on this thread! Try posting the general area that you are from and maybe there might be someone nearby you who is a member of this forum who might be able to help. Otherwise take both engines to a motorcycle shop or a small engines/ lawn mower shop and get them to give you some quotes on rebuilding 1 engine from the 2 that you have (kinda build with the best parts you have from both). Pulling the head and cylinder off first and having a look at both the piston and sleeve should tell you if you're into a big or small problem, but if doing this is above your comfort level. Then definitely take it to someone who can do it properly for you. They'll have to investigate things for themselves by pulling the head and cylinder off first to see what kinda damage has been done and how it can be repaired or most likely replaced.

Good luck.
