It's nice to know she does a turn Andy....can we all have a go with her next year?? :-)

Aye Andy,

Delighted to read the diplomacy is successful. Also that the cantankerous one turns smoothly with no clicks, clunks or grinding noises.

It's cowping it here at present.

My regards, Bill.

Aye, thanks guys!

However, I've learned the hard way that Blu Tak is no good for checking clearences.  Its.... "tacky"... funny that   

So, repeat with real plasticene.

Sorry guys, progress is painfully slow!

Modelling clay is another option, as it will go hard eventually making measurement easier. I thought I would be clever and sprayed the piston with WD40 before putting the plasticine in place. I ended up with a soggy mess.

Exactly as I was going to do!  OK then, thanks for that, you've potentially saved me from a 3rd strip down!  I will however wipe the faces of the valves lightly with oil...

May try modelling clay, but fear it would shrink slightly as it dries??  Will let you know how I get on over the weekend.

Modeling clay shrinks a lot on drying - is why I like soft solder - needs to be soft mind - as it squishes but can be mic'ed up - have never had probs with it marking the ally piston or head - guess you need to try some on a bit of ally first - see what scratches what.  Also if you are looking for - say a 0.3mm clearance - then use 0.5mm solder not 5mm solder - it only needs a couple of flats on it - does not need to be squashed over the whole of the piston.  3 tabs 120 degrees apart running from the crown to the edge, little thicker than the gap should be.  if it does not squash than you are some distance off ...
