Now I have put together a 125cc motor and put that on the utility base as I didn't have all the parts for the 160cc motor , now it goes well and is almost complete, plenty of power. 
cheers
speedy
The 125 full crank is probably the best engine Victa ever made. The more I hear about them, the more I believe the 160 was a marketing exercise. 
Good to see another one reprised.
