I think 11x6 is as small as I'd go. 11x7 or 11x8 are probably best for that engine. Those are the props the engine was designed to turn.

My 1960's webra 61 (10cc) runs best with a Master Airscrew 12 x 8 Prop, it likes heavy props:- I found wood ones
to have Idle issue and problems with midrange.

I was gona suggest a 12~6 as most of these older .60s were designed to use. The rpm may be down a bit but depending on the plane this could make a good combo. Mainly, you have to do a bit of experimenting.

If this is a 70's or 80's Silverline, i expect the 11-7 prop would be best. Especially on a pattern or pattern like aircraft.
