Combustion chamber question

[arancia]

I think that if you measure the outside diameter of the raised part of the liners and the inside diameter of the skulls in the combustion chambers you'll see that the liners can go into the head just enough to locate the head perfectly while still sealing with the head gasket.

Beware the creeping liner.
And the crap gasket.

You have high comp pistons.

You dont need two gaskets

Thanks, important questions now sorted . Now time to find motivation to put things together, which may be a challenge living in a land currently down below zero where appetite for winter activities are growing.

Btw, I checked the carbs and found a higher float level on cylinder #2 which would yield a lower fluid level (if I’m correct ) Which in turn would explain that this cyl is a bit dry.

It's the contrary, the higher the float level, the later the fuel cut off, the richer it's likely to be. Unless you're referring to float level measured on inverted carb, in which case, you're right.

This is measured on inverted carb. It’s like a 50:50 issue, the float level. With my crimpled mind I really have to concentrate deep to choose the right alternative , so thanks for confirming my choice. Fluid level would be simplerr, but for that I need to get me a translucent float bowl (I actually had one some 10 years ago on another laverda but didn’t understand the usability of it at that time ) .

Depends whether you're a float level half full or half empty kind of guy.

You need to measure the height of the liner from the deck I believe.
Must be mentioned in the archives of this forum somewhere.

Float bowl adjustment, been covered previous on this forum. I use a small length of food grade tubing, on the fuel inlet spigot ( at the carb ), fabricate a small right angle jig, with 18m/m height on inside edge, blow air into the tube, until the carby needle and seat inlet valve seals with 18m/m jig in place. I do that with the carbies on the engine, the problem is a tool to gently adjust the tang on the actual float assembly while it is installed, without warping the plastic floats alignment. Explain better if required, j.
