Hmm, don't think so.

If it looks like this

then I would hazard a guess that once you've removed the recoil starter and
pawl sub-assembly you might be able to screw bolts back into the two holes
in the flywheel on either side of the central left hand thread nut (once
you've removed it of course) through a short bar across the end of the
crankshaft. This should "push" the flywheel off the crankshaft.

You could even re-use the pawl hub sub-assembly (part 123) with something
to block the central hole packed behind it.

Ah yes, I was almost going to say that sometimes flywheels have threaded
holes for simple extractor bolts, but I thought that was going to be too
easy!

(Currently searching for my bit of scaffold pole to slip over the big
stilson in an attempt to loosen a gate hinge adjustment nut. I know I
shouldn't be using the stilson, but the big adjustable hasn't come back
from loan).
