Car Forum / MINI / October 2003fuel leak
Hi folks, jumped in my mini yesterday. Started the engine. it quit. restarted. it quit. restarted again. it quit. I thought damn it seems like it isn't getting gas. Odd because the day before, my wife, dog, and I took a lovely drive in the country to see the fall colors and covered over 60 km starting and stopping a half dozen times. I got out of the car and noticed it had pee'd fuel all over the garage floor during the aborted startups. It appears that the fuel is being pumped out of a tube coming out of the carb. ( the upper of two fuel lines connecting to the carb) This tube runs along the clutch housing and terminates along the frame near the right front wheel. If this tube was supposed to be connected to something it has disappeared completely. So I assume it is an overflow out of the carb but why is there so much overflow and why is it starving the engine? Oddly the car ran perfectly the day before. Do I have a a carb problem such as a stuck float that would cause this? Comments are welcome. BTW car is 1992. engine 1275. Thanks, Craig > Hi folks, > jumped in my mini yesterday.

It could be just a piece of muck stuck in the float valve. If the float chamber is on the side of the carb, then just remove the 3 screws on the top to remove the cover. The valve/float needle is inside the cover. k Thanks, I thought it had to be something like that. Once cleared should it be good to go or do you think I should be rebuilding the carby.

When this sort of thing happens: If it smells like gas, bang on the carb. If it doesn't smell like gas, bang on the pump. I will be banging right away after work, and let you know how it goes.

Fabulous pest control - the fumes killed the mice in my garage before they could make a home in the Mini's upholstery. \o/ > One local british car enthusiast told me this simple rule.

Right away I noticed the float was full of fuel and likely not floating anymore. Sending for a new one today. Thanks for the help.

A sunk! this new floating float arrangement should help out my gas mileage. I might start burning all of the fuel, which is much more efficient then pumping it out and relying on Newton's opposite and equal reaction law for forward progress. > > Aah, So you didn't have a float, you had a sink! > > A sunk! > > A sunk! > this new floating float arrangement should help out my gas mileage.

If the car was tuned with a half sunk float, then it will run lean with a healthy float. Check the mixture after reassembly....
