I have been asked to fix a Victa 2-stroke run without pre-mix - eg on straight unleaded. I believe it may have siezed, but has freed up, has compression and spark. I haven't looked at it yet, but I suspect that if it has both these, it is a fuel or crankcase seal problem. Any suggestions before I attack it would be greatly appreciated! I think it is around 5-10 years old, if that is any help.
