I think the Worlds S7 was purchased in the 90s. I need to check to make sure it's not rusted. . I kept it in a cool place with oil in the engine.

Ball Bearings for Nitro R/C Engines - NOVAROSSI WORLD

You probably need the 16009
The SLS is the super long stroke and in that time they did come with special bearings.

If you are handy or know someone who is, you can modify the crankcase to fit normal bearings

Just as an update to previous questions on here and to clear something I have been asked a few times, the old RB 01122-C Con rod has now been superseded by the Novarossi 07014 Rod for anyone wanting to rebuild their old motors. This has been mentioned above but i dont think anyone ever gave the part number.

The WS7 was a Novarossi based engine. Stock, they came with "standard" head, but a turbo head was an option. RB went out of business a while ago, so finding parts isn't easy... However, as far as plugs go, no need, as most standard plugs will fit. Like previously stated, a Novarossi standard "6" plug should be perfect, in colder weather (under 55* F) you might try a "5". There can be allot of other things that will effect your engine, but if you use a "6", it pretty much works all the time...
