    Yes he does have an O&R with the Octura rotary valve (& water cooled cylinder), but it was a bit camera shy when he was restoring it , hopefully another will turn up eventually as I wouldn't expect it will need opening up anytime soon. It's now in the White Heat in the first post here; David

    I only sent a message to advise them it was not as described, they wouldn't want someone to claim for this when it arrives and is found not to be an O&R or Orline. No interest in buying at that price even if it had international shipping, same goes for the actual O&R powered tools he has. David

    I can't tell you exactly what the rotary valve looks like as I haven't seen the parts, but it will be something similar to rotary valve used on the pre-Compact model engines. The reed valve assembly & PTO shaft will be replaced with parts with holes machined into them, to allow fuel through at a certain point in the rotation when the holes in the bearing plate & shaft line up. You can see the hole in the crankshaft that lines up with the carb port in the sectioned Ohlsson 29 engines. And the crankshaft has a hole through to the crankcase as seen in my Ohlsson 60. Many more engines had the Octura carb fitted than the rotary valve, it's entirely up to you if you want to use one or not, note the fuel tank cannot be fitted the carb above as they sometimes are, unless you want the fuel to slowly leak out through the carb.
