Ok I'm going to post it like it is.
Crate Motor $300 @ 1977Mopeds.com
Your Motor $220 ~ Needs a new head, needs a crank because a stock crank can't handle the 70cc, needs a new pipe because the SIM Circuit is the worse possible choice for a pipe and it's broken. It would be better with the stock Blunderbuss, needs a variator because who the fuck wants a single speed non-variated Dimoby clutch when a vario goes in the same crank (which needs to be replaced). Your carb bendy adjuster is broken and I'm not sure if that is even a real Dell (dull aluminum looks like a clone).
So all together you have a nice kit that is used ($125-use=$1/2shipped), maybe a real Dell 15mm SHA used ($25-$40), maybe a good ignition ($25~6v/$30~12v) because CDI's are cheap, and you have cases which could be fucked if you don't know how to case match correctly. These would be worth more uncut ($50)
parting it out would be useless because shipping would destroy any possible gain so consider what a stock engine is worth ($70-$100) and add a little extra for the kit/carb. If it does run I would be on the high side of that even though it needs work if the buyer wants it to last at all. The loose head will destroy a lot.
