Question 1991 CR 125 Top End??

Hey everyone,

I recently bought a 1991 CR 125, Runs pretty good, Starts first kick, but there are a couple of issues I was hoping I might get some help with.

1) There is quite a bit of Oil/fuel Mixture blowing out of the exhaust right next to the Flange, New gasket? or new top end? I have heard when compression is low the oil part of the mix will not burn off and it just sort of drips out of the exhaust, is that what I am seeing all over the front of the motor?

2) it seems the chain is very loose, Can I just loosen the rear wheel, and slide it back to tighten it up some?

3) The bike will not idle, you have to give it a small amount of throttle to keep it running. carb probably not adjusted properly, where should I look to
get enough fuel flowing to let the bike idle?

Thanks in advance for any help!!
