I might suggest you remove all of that emissions crap. Do a search for PAIR removal. I did this 6 years ago, before starting my scooter for the first time. That was 13,600 miles ago....scoot has never failed to start or run correctly.
My scoot is very similar to the Heritage....handlebars, and headlight are about the only difference. The photo of my engine compartment after Pair removal is below. This action will make your scooter more reliable.
