i have a older pressure washer from campbell hausfeld it has a 6hp briggs motor and i have had a problem with it leaking fuel. well today i decided to see what was wrong and the fuel is leaking out of the front of the carb where the filter is. i opted for a new carb rather than rebuild what i got. my question is, is there anyway right now with it leaking fuel to see if the motor indeed is good before i order the carb? when i tried pulling the cord before it only comes out a few inches and thats it. is that normal. this is not my pressure washer so i am not used to the normal working of it.
