As a temporary stopgap I have used a windscreen fitting "glue".

it's called "Tiger seal".

Since windscreens are not subject to contact with fuel on a constant basis I doubt if its designed to withstand petrol for long. If it turns into "gorilla snot" it could affect your carburettor plus not all sealants are cat friendly, could damage that or the oxygen sensor.

Why not spend a few pounds on the right part. Bodges like this are not the solution a responsible car owner would use.

Oxygen sensor on a car fitted with a Carburettor? ;)

In my deffense of using Tiger seal,

It was late Sunday,

So nobody was open,

Well except me,

So no part availability not even breakers.

Owner had a 50 mile drive to get home.

middle of nowhere if I recall right.

And repair was done with full permision from said owner.And they made it home.

Point 2.

this flange gasket is AFTER the carb so no possiblity of gorilla snot getting anywhere near carb internals.

Point 3 would be me fotgetting to seal up said tiger seal on a few occasions and finding next day a tube of what can only be described as SOLLID RUBBER!

Though next time to be sure I'll drop some in various solvents and check the results.

Point 4 would be the sealing is against air bypassing the carb and weak mixture the result which I found to be fairly common on the old VW carb engines.

All you had to do was lean gently on the air fiter housing to check for RPM variance.

And finaly the guys in the back of beyond!

And I just offered him a temporary solution.

Call that a bodge if you want.

I'll take that as "bodgers" are highly skilled pole lathe turners making usually turned chair legs on lathes powered by their of legs in the middle of the woods somewhere.

How these craftsmens trade name got twisted is beyond be but it has.

Try" you tube" for a look at what a bodger really does.
