Wow,thank you for your knowledge.
It helps!

Also i want to ask you if you have any experience with SP series???
i saw the 91 and 120 SP and thought if you can start them by hand(???) or with a regular glowstarter?
And another question:
RCV engines are "English" engines.I mean there manufactured in the United Kingdom?
Also in comparison to the OS 91 Surpass what do you have to say?{I mean compare the RCV 91 CD vs OS 91 Surpass}.
