Berk!! Just stripped carb for cleaning, and laid all jets etc out on card to replace in reverse order. Tipped the lot up! Can't remember in what order the 2 jets that mount in the top of body go. when seated and looking out to the engine, is it the larger or smaller one that goes close to engine side one is 120 & one 160.
if you have the exploded diagram of the webber32/36 parts no 79 & 79a. thanks

the 120 will feed the 32mm venturi and the 160 the 36mm venturi.

Brilliant. It's a relief to know I'm not the only one who drops washers down a drain or falls over the carefully arranged in order line of bits or wanders the garage in a frustrated rage looking for the spanner I left on the toilet window sill when I nipped in to have a pee earlier.

thanks pete, getting my calipers out now
