Question about Garden
I have a Husqvarna...Code TJ7027D-BC55..I was wanting to know if there is a different carb that I can use on this machine, such as a Walbro/Zama? The one on it now is a TK TZ-11, can not find a carb kit for it, only individual pieces, one of which is $20.

If the float don't float, the needle valve stays open and gas runs into crankcase.
If float floats (has no gas inside) then the needlel is probably worn and needs replacement.

The problem centers around the carburetor. The question lies in the condition and operation of the carb initially.
It appears you may need to double check your assembly of diaphragms and gaskets. check for loose welch plugs, adjustment needles in the wrong holes, inlet needle set too high.
*note: metering side diaphragm goes on top of the gasket, fuel pump diahragm has the gasket on top of it.

For a machine with a remote primer bulb: The small diameter line out of fuel tank (has filter in-tank on end) connects directly to the side of the carburetor that has the fuel pump....that is the cover without the hole in it. Other larger diameter fuel line out of tank connects to the longer nipple on the external purge/primer bulb. The bulb "pulls" fresh fuel from the fuel tank to the carb and then out of the carb to itself, where it then "pushes" any air/old fuel back into the fuel tank. The remaining larger diameter fuel line in this setup goes from the metering chamber (has cover with writing on it and a vent-hole) side of the carburetor to the smaller nipple on the purge/primer bulb. Again, on the primer bulb, the longer nipple has a line going directly from it to the tank. This is the return line. The shorter nipple on the bub has a line from it going to the metering chamber side of the carb. For a machine with the purge/primer bulb on top of the carb: The small line from carb body to small hole in tank with filter. Larger diameter line goes from the bulb on the fuel pump side of the carb to the larger hole in the fuel tank where sometimes the line is held in place with a nylon nipple connector that keeps the line from pulling out of the tank. Otherwise, the line should enter the tank for about 1/2" or so.
