    car guys/mechanics/small engine guys Carb QUESTION

    What is the issue when you pushed the primer bubble and instead of fuel going from the fuel line to the carb when you push the primer bubble it puts air into the gas tank? does 180 of what it's supposed to do

    I am using a walbro carb.

          I think this means you have a diactical split in your bores.

              if existing carb, I would guess a diaphram went bad

                nope it ran and it sat and I fucked up the carb air/fuel ratio and it sat for more and now we can get it to fire right up. if we spray injector into the carb problem is no fuel from the gas tank is going to the carb and the lines seemed almost swaped

                  Your dangfangle is arbitrarily disconfobulated from the siamic dretomachination.

                  I'm almost 100% sure of it.

                    I am going to make a few guesses

                    1. cracked diaphram in carb (causing no vacuum)
                    2. bad fuel pump

                      It might have to do with a microscopic hole in the line letting air in.. if that sounds close thats what I have researched so far

                        Put it this way, when it comes to vacuum, holes that are blocked, or that are there and shouldn't be, will always cause trouble.

                            there is nothing microscopic about a hole that shouldn't be there.
