Johnno, pull the decompressor out (19mm spanner) and screw a spark plug into the decompressor hole, then give the pull starter a pull and that will give you an idea of the compression, you maybe surprised.

To test the decompressor in your hand, suck on the plastic tube end and watch the plunger suck in and keep sucking you should not be able to suck anymore.
