There is a really strong smell coming into our std 850, after about 5 minutes driving. I'll do a little research, but it's hard to tell if it's stronger when cornering or not.

It's coming from the carb ro nearby, so could it be:
(a) worn carb which leaks petrol
(b) something else.
(you can see I haven't done much detective work yet...)

If you have a mechanical fuel pump then check that it is not leaking from the cap. I have had 2 minis leak fuel from there.

Is there an visible leaks on the ground if idleing for a while?

First thing i'd do is undo the 3 screws on the carbie bowl and check that the float hasn't got a hole in it or if the float valve is working right.

Mine did that and found fuel oozing ou tof the Mech fuel pump

Just for the record, the smell was coming from a loose float bowl. As it was so loose, the float bowl was tilted back about 30 degrees. So I made it level and tightened it up. So no smell of gas, and no bogging down in corners - it's like a new car.

I was so buoyed up by my success in fixing the mini, I fitted my new horns to the Commer. PARRRRP! But there's a downside to every Fathers' Day. In this case, it was looking after 2 other kids as well as ours. For some reason, our kids are darlings and everyone else's are little pr!cks...
