engine locked up

[nadroj]

i dont care. if you are going to tell me about the dangers of no filter you dont need to post here anymore. I obviously understand them.

for the cylinder I do need to pry it off it is not budging.

Might see if you can remove the studs. It can make it easier. Double nut the stud and turn counter clockwise.
You may need a new cylinder besides rings. Put some oil in cylinder and work it a bit.
Good luck.
Is the head a slant head ? As long as your getting parts may be something to think about.

so i got the cylinder off and guess what i found. some where in the crank it is jaming up. the piston and rings appear to be fine. what could have causeed the jam? I am just going to buy a new lower end because mine wasnt doing so hot already. but wow/

Residual Oil In Crankcase?

Can you see any residual oil in the bottom of the crankcase? One of the two stroke gas/oil mix experts said there should be around 3cc of oil in the bottom if the mix is right. Also what is the color of the plug? Oiley, sooty brown or chalk white? Proper mix would have it sooty brown. (Dry but not burned) Then is the conrod free to rock back and forth on the crank? Have you looked iunder the clutch cover? Maybe something is wrong over there? Finally how about the magnet and mag assembly? Something there could break and jam the crank.

I am not much on 2 strokes, just playing with my first one that someone gave me, but I have gotten a lot of good info on them here. Always worked with 4 stroke and these are really different. I don't think my early years with O&R and OK Cub model airplane engines count?

Good luck
