Stihl 090 10ci 10 cube
« on: January 11, 2017, 12:25:13 pm »
I know I had a thread on these ole stihl 090 10 cube saws somewhere  :-\. Maybe it was in the  racesaws days.

Anyhow here is a big bore 090 a ole racer is getting restored and rebuilt from the racing days.

The pic is the 10ci piston on bottom with a 66mm on top.

OOOF!! That would be a real beast although the cylinder walls must be very thin. What carburetor would work on something like that?

The orignal standard HL Tillotson were usually used with the venturi bored out oversize. Hans Peter Stihl as a young man in the 1960's got heavily involved in the Go Kart scene with the Contra powerheads.
There was many more 10 cube 090 P/C's built then what we were told.
Alot of them got into the ultra light aviation field plus test model saws into the African jungles.
Making a living with a saw since age 16.

Just my WAG many years of not flushing real good.  Getting all the alky/nitro out of it on the flush.

Also surprised how thin the top of piston is over ring. Seen thicker then that break.

Hi Kevin and folkz, been a while since I have been on this forum... Be real nice to find one of those beasts hidden somewhere, there must be a couple out here in Oz.

That piston looks to me like it was set up for a Dykes ring, unlike the 66mm slug. Interesting.
