Stickies Lambretta book mixes its torque measurements between foot/pounds and kilogram/meters and my Facom torque wrench is in Newton/meters.
I made this conversion chart to list all three in a range of values suitable for a Lambretta engine build. I’ve stuck it inside the front cover.

UPDATE : Awww crap! I just found a very similar chart in the Appendix of Stickies book!
Another (small!) parts order arrived this morning in a deluge of post after the long weekend. It was only a couple of oil seals and gaskets which I’d forgotten in the last order but it came beautifully packaged from MB Developments in a tiny cardboard box which was positively Japanese in construction. I got the Mag bearing and oil seals fitted (with some extreme blow lamp action on the engine casing and the bearing in the freezer) whilst baby sitting and then halfway through the in-laws arrived a day early!
I received my latest parts order last week. The 186 Mugello kit came back into stock at CamLam, I sent my order at 12:18 and got an email back to say it had been dispatched at 12:38!
On opening the package I noticed that the cyclinder head was face down in the box with the domed inner side resting directly on the skirt of the barrel with a thin layer of polystyrene between both parts. The head has received a couple of knocks in the post causing two dents on the face. You can see the two dents in the image below.
Kurt on the forum at lambretta.be said :-
Maybe the damage isn’t cause in the shipment?
My opinion is: that it is common practice to use parts with little defaults, (maybe already returned by other customers) for (int.)mailorder customers.
I also expirienced this before on a few occasions (not with this supplier here).
That is just the odd side of mailordering parts if you ask me.
The seller knows also, what you already conclude for yourself, due to high shipping costs you’re not willing to send them back for some minor defaults and you will try to find another solution.
But you did payed the full sum!
It’s a shame that not more suppliers offer these light-damaged parts with an extra discount instead of selling them as ‘new’, that would be far more customer friendly especialy on longterm.
Conclusion: Buying directly in the shop or at a fair still has it advantages.
On the photo it looks that the sealing area isn’t touched but it is more into the combustion area. Maybe you can use some mild wet-sanding paper to clean this up.
I had an email reply from CamLam and they said the same thing :-
“Hi ben it looks fine as the gasket face is untouched and purfectlt flat which is the important part so yes go ahead and use the headwith no worries regards trevor”
Irish John suggested :-
“Flat” the head beofre you use it and it will be fine. Use a mirror or a piece of a broken one, some light sand paper and some water or dreft (fairy liquid). 40 turns to the left, forty turns to the right (some people use another method) and you cylinder head will look like new. Do this after you have worked on the scratches in the combution chamber.
The dings cleaned up well and then I did the “flatting” on a piece of glass.
