Hi John,
I thought maybe best to start a new post with my findings, and my answers, as i feel this may rumble on a bit, and i have hijacked this post enough already ! Hope you read my findings - your help is invaluable right now!

I soldered up the poppet valves on the last 'S' I had. As long as you get a good fillet of solder right the way round each valve there should be no leakage! Everything being brass meant it was an easy solder to do.

Cheers, Mike.

That thought did cross my mind Mike... now you have said that yourself that may well be the way to go....did you notice any improvement on doing that ? How are things going with the P.I.?
As an afterthought, i assume you left the valves in place, and soldered around them, as oppose removing them from the flap?
Cheers, Nige.

Hi Nige,

With 'plain' discs the engine seem more responsive, especially on the 'overrun'. I don't remember if I did them on or off the carbs (it was a long time ago!), I'm not sure how much access there is when on the carbs. It is important to get a good fillet of solder all the ay round or they might still leak air!

No progress on the PI recently, but I'm hoping to get back onto it when it warms up a bit in the garage. Whenever Six Appeal arrives I get a bit more incentive.
