using to much petrol

[joshspragg]

my mates mini is using too much petrol or something, he thinks it could be a problem with the carb. anyone know what it could be causing it?
its a 1994 mini sprite 1275cc

[ljonez]

What sort of mpg is he getting ?

Most of the time its the driver not driving efficiently

[coedy]

And where is he mainly driving? Motorways, A roads, city/town?

Any mods on the engine?

etc etc etc

[joshspragg]

well he drove about 10-15 miles and wasted quarter of a tank. no mods. the car before he had it was sitting there for 2 years if thats any help.

Assuming it was giving OK fuel consumption before it was layed up for the 2 years, it may just need a good thrashing up and down the motorway with a couple of shots of Redex in the tank !

Other obvious things to check is perished fuel lines or dripping petrol when the engine is running

[joshspragg]

ok, i'll have a chat with him.

After general checks, a rolling road session would be a good idea.

[joshspragg]

well i just seen my mate in school and his engine was running and all i could smell was a really rich smell of petrol. so i doubt its his driving or anything. anyone have an idea?

[jackdaw]

That can only be a fuel leak or the engine tuning is way way too rich

[joshspragg]

right ok. i'll let him know. thanks,

[jackdaw]

If the smell of petrol is all around the car, engine bay, inside etc then I would be looking for a leak.

If the smell of petrol is more only from the exhaust fumes - (try holding your hand about 15 inches away from the exhaust pipes for a short time while he revs the engine a little then smell your hand for the petrol smell ) then its engine tuning.

As Tim suggested, a trip to a rolling road will sort it out plus get the Mini running as it should.
