Excessive fuel consumption

[jonoy]

I recently brimmed my tank

Only ridden about 10 miles
Went to top it up for a trip tomorrow and it's
took 5 litres of fuel
No leaks visible
Any help

Unless you have a leak (remember that petrol will evaporate leaving a 2 stroke oil residue), I can't believe that any Lambretta 2 stroke engine could possibly do 2 miles per litre.

Must be a leak .
If it was me I'd park it up With some cardboard under the central area and fill the tank to the brim put the tank cap back on.

Leave overnight Say and recheck.....
