Thanks to you both.......you are confirming what I thought.
To be accurate RCS came good on the warranty and sent me a new engine immediatley without return of the damaged one.
Im trying to make up my mind whether to return it to them or buy it at a deep discounted price they will give me since they dont market the model any longer,and repair it........parts arent a problem since the 44cc twin is two cylinders of the 22cc single they still sell.......and its available in europe anyway.......
