3W-140 Problem

[Keith Mitchell]

Does anybody know what the adhesive/sealant is that sticks/seals the reed valve housing to the inside of the crankcase?

Cheers,
K.

I've sorted the problem (rough running, poor starting). It was in the joint between the crankcase and the reed-valve frame. The original jointing compound was failing allowing leakage around the reeds.

Cleaned-off the old compound and re-jointed with 'Universal Blue' (Hyalomar) - available from motor factors. It is a sealant/jointing compound that is impervious to virtually all industrial fluids and works up to high temperatures.

The substance has an interesting history. Developed by Rolls-Royce 40 years ago for sealing joints in jet engines, the patent expired 20 years ago and RR stopped producing it. A German company obtained the rights and now make it and sell it all over the World.

Why don't we make anything anymore --------------?
