When I wasn't able to find the carb dust cover for the OS .12 CV, I found another complete OS .12 CV non-pull start motor, listed for sale with no compression - the seller took $40 with free shipping.
This CV looked way too new and clean in the seller's pics, to me, to have compression problems:
When I first tried, I could easily turn the shaft with bare fingers, and it felt like a gritty/dirt filled slip, with 0 compression.
The bottom end, crank/con-rod/piston/front bearing, are all like new in there:
When I pulled the head off, the sleeve came out with the head, stuck to it. Also noticed there was no shim/metal spacer between the head and the case?! Could the sleeve have come out of the case because there was no shim/spacer?
The sleeve itself looks like it's still in great condition, it's just out of the case somehow.
Got the engine all cleaned and ready to put the sleeve back in.
What holds the sleeve in the case? I've seen that you need a special tool to even remove the sleeve, so I can't figure out why the sleeve is out, and on such a new engine. How can I be sure the sleeve won't come out again, or how do you fix it in place?
