It is highly likely you have a sticking/dirty needle and seat in(one or both) fo the carburettor/s.
I quick trick is to loosen the carby drain screws( located at the bottom of each carby) and as the fuel drains out, tap the bowls with the handle of a screwdriver. This is often enough to loosen the blockage and your leak will stop.

Otherwise, if the leak continues, you will need to remove the carbys, and clean them taking particular attention to the needles and seats and replace if necessary.
Afterwords I strongly recommend you fit an in-line fuel filter (if you have room) for some added protection from the problem re-occurring

Windchaser PACR9 troubleshooting

Hi Jeff,
There is an air leak somewhere inside.
  • Check that all windows are properly shut.
  • If the unit has an air exchanger, make sure it is closed.
  • Or there is a lot more Moisture (Humidity) in the air inside your quarters.
  • Check for massive dirt ( dust) build-up on the condenser or evaporator.
  • Lastly, do not forget to clean the filter too.
Good Luck!

My car smells like gas in the inside of it. What could be the problem?

you got a gas leak somewhere and when you travel your pressure on the inside sucks the fumes in. try opening your vents for fresh air from the front of the car. i had the same problem only if my window was open.

Why does the air conditioner leak water from behind the unit. My air conditioner is placed in a wall and the back end of the conditioning unit sticks out inside the garage. I have ventilation by...

It is normal for an air conditioner to leak water out the back. This water is actually the humidity being taken out of your house. Being vented out in to the garage is always an issue with condensate water. I have seen some people take a funnel and run a hose outside the garage somewhere. Keep the vent closed. It will be harder to cool the house with the vent open because it lets outside air in to the house.

It drinks a lot of gas ..i put $20 in my tank and after 35 miles i have to put more gas in my car . i already had a new fuel filter put on ; all fluids changed . ....... Whats Next !!!!!

Unless gas is leaking somewhere all the gas a car uses goes through the injectors. If it uses too much fuel that means the injecters are being kept open too long or it is being burned improperly or engine load is extremely high. Unfortunately it can be a pretty complicate process to figure out what the problem is on a computer controlled car. It taks some rather sophisticated equipment to monitor the engine sensors. Are there any codes stored in the ECM? Is the air filter clean?

I Have a Stanley air compressor Bostitch model APC-OL6-UK it is spitting brown liquid how do I clean this please

The brown liquid you are getting out of the compressor is water with rust in it from the inside the air tank. Somewhere on the bottom of your air tank there is a valve you need to open from time to time to drain the water from your tank. If you are getting rusty water from the air outlets you probably have a lot of water in the tank. If you can take the compressor outside, with pressure in the tank, where the water won't stain anything and slowly open the valve to drain the tank.

Water dripping from airconditioner inside the house

Water leak is the common issue in split a/cs. Due to coil,air filter, drain pan dust blocked, less rpm of blower motor, short of gas.
If service for the unit is more than 4 months, please do it first. And then check rpm of blower motor, if less replace capacitor.
Check gas pressure. Must be 60 PSI @ 98*F, of ambient temp. If less than that find leak and arrest and do gas charging. Thanks.

Bubbles coming out of the holes in the side of pool, when filter is on

The 'holes' are the water returns?

Air bubbles are are going back to the pool because there is a leak somewhere on the suction side of your circulating system, I.E. somewhere between the skimmer and the pressure side of your pump.

First off, you must bleed the air from your filter regularly. There should be a bleeder at the very top of the filter.

Next: Please check the strainer cover and all plumbing connections. After you have checked every thing, you may want to use silicone grease at each opening or joint in the suction side including the plumbing fittings.

I hope this information has been of some assistance to you.

As a Certified Pool Operator (CPO), I maintain several public pools. I had a devil of a time finding my leak. Turned out it was the fitting where the suction line entered the pump housing (at the strainer). I found it using the method I suggested to you. No amount of teflon tape would stop the leak, but the silicone grease (available at pool supply place as "O" ring lube) took care of it.

I hope you have success plugging your leak. Thanks for posting your question at Please remember to vote - it is important to we volunteer workers.

Water leaking from refrigerator...

You may have a small hole in the internal water pipe. Possibly from rubbing against the motor.
Take the end of the pipe comming from the back of the fridge (water inlet) and blow as hard as you can into it. If air passes through then you have a leak for sure.
Get a second set of hands to run along the pipe while you blow and you should be able to feel where the air is comming from.

Had this problem years ago with an Americana double door with ice dispenser.
