Don't use general purpose silicones here. There are a couple of types available, made for sealing motorcycle cases, that would work, but a solvent-based non-hardening 'gasket cement' is what Victa always recommended. Permatex #3 'gasket sealant', which comes in a bottle with a brush top, has always worked well for me. Any automotive parts shop will have that.

To absolutely ensure that the joint seals properly, you could lap the sealing surfaces. This just requires a sheet of 600 grit wet and dry abrasive paper and a really flat surface [e.g. sheet glass]. Wet the paper [with water is fine], place it on the glass, and move the crankcase half in small circles until the sealing surface is uniformly bright metal. Rinse off with clean water, dry, and it's done.

Will deffinitely be on the lookout for one.. though Im gonna give it a shot to see if i can correct it.. just in-case, are these crankshaft used in all the older 2stroke victas ? or is each different ?
If the bend is only at the start of the threaded section, as it appears to be, it's quite feasible to straighten it. The best way is with a press, a set of vee blocks, and a dial indicator and base.

On another note, the bearings look exposed (no rubber seals on them) .. when I replace them, do I need to get the same deep groove radial bearings? Does the oil in the 2 stroke lubricate them or will sealed bearings be ok ?
Yes, open bearings are required, so that the oil in the 2-stroke mix lubricates them. The correct types aren't that exy anyway; 20mm x2 HERE and 17mm x1 HERE

The big concern here, with the amount of rust on those old bearings, is the condition of the conrod big end rollers. Does the conrod rotate freely and smoothly, or does it feel a bit 'graunchy'?
