Thats fair enough, but this one might not be as corroded. Some of them just slip right off with very little effort. Others take a lot of work and a puller becomes the only option.
Does not hurt to try before going to the trouble of buying a thread tap and some bolts and buying or making a puller.
I do not suggest the hammer either, i have been known to get my hand under a briggs flywheel and tap the crank but i would not do that on a victa as it is not on a taper.
