Well, I have all the parts aside that are needed to fix it up, as ling as the engine itself is good. (I have base, cowl, wheels, ignition, carby, blade disc, starter, and even handles if needed)
I'm not sure about the utulity claim there bob, personally i feel the Series 80 is just a series 70 with a crap starter. the electronic ignition of the MKII seris 80 is a plus, but the rest of them really is just a series 70 MKIV.
Bu then agian, I guess it all comes down to opinion!
