Paperclipped and just came up with 12 and 31. No signs of leaks when spraying carb cleaner with engine running.
I cleaned the breathers as per guide including vent housing - the small pipe to the housing was clear but just put a pin in there to clean it and a squirt of carb cleaner, the larger one i could not get off so i squirted a small amount of carb cleaner into left side big pipe (i blew down it first and seemed clear) and the other large breather pipe.
On the breather box the "pipe" that leads to the two small holes on the box had quite a bit of carbon come out - this was cleaned to within an inch of its' life!
Then did an oil change and to get the oil warm let it run for a couple of minutes - it was popping / stuttering all over the place. Thought any gunk would come out with the old oil but even after the change it is still popping (though not as much as before).
I double checked everything was put back together correctly and i believe it has been. I couldn't see where the other small breather pipe connects to - it looks secure but could not follow its' path - where does it go?
I hope i haven't messed it up by squirting carb cleaner down the big 2 breather pipes but the engine is popping like its bonfire night
Any help / pointers much appreciated
