After sorting the seized gudgeon pin, I took out the valves as they didn't seal properly. The inlet valve had a patch of rust that left the seating face badly pitted. There was a flake of rust stuck to the seating face in the cylinder head, I got this off with a bamboo skewer and WD40. HobbyPlastic stocked the valves, they come in pairs. Order placed Monday morning, valves delivered Tuesday morning. After a final check of everything I could think of, I reassembled the engine. It had its first run on Tuesday afternoon, it was reluctant to start at first, probably due to the generous amounts of oil sloshing around. Reset the carburettor to the info on the Saito website. Now starts easily and throttles quite well considering that it isn't run in yet. During my search for Saito information, I came across this thread, its the most informative easy to understand piece I've come across. Anyone who still has a Saito engine might find it a useful read.

During the running in process, there was a lot of oil coming from the crankcase breather. I copied the OS system and routed the breather tube so that the exit was pointing into the carburettor intake. Doesn't seem to affect the running, and now all the gunge comes out of the exhaust instead of over the test rig, and the engine gets some extra lube and the garden fence gets a coating of used oil.I still haven't managed to convince my wife of the weatherproofing benefits of old engine oil on garden fences.

Brian, this is hardy relevant to the Saito, I should have posted it on your Hannibal topic, so will probably earn a rebuke and go into negative Karma but now I'm here congrats on getting your letter published in the latest RCM&E!

Thank you David. The Saito and Hannibal are more or less linked, but they won't be together until the engine is run in and converted to petrol.
I wonder if there is such a thing as negative Karma? I think of it as either "Karma" or "Not Karma", but perhaps I'm influenced by my working career.
On a brighter note, my neighbours are no doubt quite pleased that I'm not running a noisy engine today. I'll make up for it when the rain stops.

You don't have to look very far to see that negative karma definitely exists.

Well I never! Still, perhaps better a negative Karma than no Karma at all.

Whatever have you done to deserve that? Tut! Some people.
Don't worry though, I think there was a competition to gain the most negative. I thought we had passed that phase but apparently not.

I wasn't looking when it happened Phil, anyway I don't think it was meant to be unkind. Perhaps if I manage to get to the field and fly something, then it'll be taken back. Strangely, I still haven't found an explanation of "Karma" that I can understand. Once I tried to read a book about it, well I thought it would explain it. But it was all pictures of people doing impossible things. I had to give up. All too confusing.
