What does the original MKII-130 chopper assembly really looks like? I'm aware that everyone here knows the what does a Hurricane chopper assembly looks like but the thing is, it's the assembly of the old square Hurricane 130 or mistakenly called as "MKI". The yellow one in Darien IL that was removed and sold at an auction in 2010 has videos of the chopper assembly uploaded in YouTube but that was not the original MKII-130 chopper, it was a re-used 130 / MKI chopper assembly which is exactly the same chopper found square Hurricane that was removed in Centralia, IL. ACA apparently produced MKII's with different chopper assemblies with the same port ratio. The original MKII-130 chopper, according to the ACA manual, has a 1 HP motor compared to the 130 (square horn/MKI) which has a 2 HP motor manufactured by Doerr.
It would be great if someone here has a photo of the original MKII-130 chopper assembly, there isn't a single photo of it uploaded in the internet.
