We have spent the last few days trying to fire-up this little engine but all attempts have failed.
It would cough and splutter but just not run so after doing the usual stuff like carburettor, point's, condenser, coil, plugs ect we checked the compression.
We found 80psi on one cylinder and 60psi on the other so although it sounded like it had enough compression and it was "sucking" through the carb, it was actually border line.!!

We stripped the cylinders down to investigate the low compression.

And soon found the problem.

It's been a long time since I'v seen piston ring that gummed-up.

After soaking them in diesel over night and applying plenty of heat they refused to budge.
Finally all the rings had to be removed with a hammer and small chisel not ideal but needs must!.
