Picked up a MotoVespa GT 160 the other day and it's boxes of bits
There's the original femsatronic 160 engine but missing it's barrel, carb and flywheel.
Are these parts interchangeable with a 1959 VBA1M 150 engine that was also in the boxes ?
How hard would sourcing the correct parts for that 160 engine be ?

Hi Mushroom.Got lots of Motovespa 160 engines in my graveyard let me know what you need and i have a rummage for you.

Thanks, but I'd given up all hope of finding anything.
I eventually bought a P200 engine to rebuild and put in there
