Slowly am piecing the 125 back together. I now have it on at least the right frame, but previous to this it was stood 80% complete for a few (read 8+) yrs 
Today i dug the engine out of the shed for a brush up. It was sort of covered in a gooey/tacky coating and at first i thought me mam had dropped a tin of varnish on it. I soon realised it was congealed 2 stroke oil
Now i know its not petrol as the engine was only run 10mins max after a rebuild and then it was completely drained of fuel.
So i set about cleaning it up off the cases and wondered where it had leaked from? Round the bottom of the reed block and intake sort of gave a clue as it was still wet. No prob, as i have probably averted a disaster, so i now know it needs extra sealing round there
Decided to whip the intake rubber off and have a look through the intake (see if i can see the bore condition. All sounds mustard turning it over on the bench, very smooth.
Which isn't really surprising as the bottom of the crank cases is full of 2 stroke! Right up to the bottom of the intake port
Am now sort of concerned why the oil has drained into the engine i've never seen that happen before and although a great rust preventative i dont really want it happening all the time. Plus she's gonna smoke like a b4st4rd when i get to fire her up!
Is there some type of check valve in the oil pump maybe?
