You could A, have completely shot piston rings, or B have bad valve seals which is probably more likely your problem, quick easy fix, just pull a valve cover, remove the rocker arms, get a small spring compressor and remove your valve springs, then replace your seals and your good to go.

Just don't let the valves fall into the cylinders when you remove the spring retainers! Yes, it can happen!

Don't forget worn valve guides!

One way to stop the valves from dropping is to use a length of clothesline rope stuffed into the cylinders one at a time. (Yes, this is for real!)

If you have an air compresser, you can buy an attachtment that allows you to pressureize the cylinders, preventing the valves from falling down.

Woops sorry about forgetting that part, I did the same thing 6stang7 said, This would also be a good time, to check for any particular leaks, If you feel alot of air coming out the breather, you may have bad rings, if it comes out your exhaust it may be your exhaust valve and carb may be your intake, Your going to need enough air, that when you hook up the line to the spark plug port, it will drop the piston to BDC. Good luck
