Two fuel lines come out of the gas tank. One has a black tab on fuel line. Is this the primer hose or main fuel hose?

SOURCE: viper engine on my earthquake tiller starts fine

You probably need a new coil, if it is a 2 stroke then it will almost certainly be the coil. The defect is very typical and recognizable.

No, it is a return line to the tank from the primer. It sounds like the hoses are reversed. The fuel should flow from the tank via the main fuel line (with the filter)( sometimes the main line is smaller than the return line) to the carb, fills the carb then to the primer bulb, and from the primer bulb back to the tank. With just enough fuel in the tank to cover the fuel filter start pressing the primer bulb. Check for fuel coming out the short hose into the tank. If instead the bubbles come out the filter and the primer goes dry try reversing the lines at the carb and/or the primer bulb and try again until you get the proper flow pattern.

How to replace fuel lines on homelite ut20811b gas trimmer

If there are two different size lines in the tank the smaller one is the main fuel line. The main fuel line will have the filter on the end of it in the tank and the filter should lay flat on the bottom of the tank. The main line will go directly to the carb on the fuel pump side. It is very difficult to describe and I dont have a way of giving a picture. If you have had the carb opened up the fuel pump side is the side that is mostly flat with holes and the dighram with the flaps.
The other nipple; usually more toward the center of the carb body, will go to the primer bulb. The primer bulb will have 2 different length nipples. The longer one is out to the tank, the shorter one is in from the carb. There is no need to have more than a half inch of line from the primer into the tank. when hooked up properly; as you press and release the primer bulb it will draw fuel up the main fuel line into the carb and fill the carb with fuel then from the carb to the primer bulb and fill the primer bulb with fuel then the excess fuel will be returned to the tank from the primer bulb.

Need a diagram of fuel line routing

Right you have three hoses, there are two holes in the tank unit, the smaller of the two holes ( too the left hand side as you look down on top) this is the main fuel hose which has the fuel filter on the end in the tank, this then fits to the right hand connection on the carb, there is then a short hose which connects to the carb on the left hand side, and then goes to the shorter of the two connections on the back of the primer ( suction side ) there is then a hose from the longer connection on the primer( pressure side ) back to the hole to the right hand side of the tank , so to recap the primer pulss fuel from the carb, into the primer bulb, and dumps back to the tank.

Wont start

I would check your fuel first. Replace fresh fuel, check fuel filter if equipped, check fuel line to not be clogged. When trying to start make sure fuel is getting to carb. If after checking all the above, it still doesn't start, I would check the spark. Make sure you are getting a spark, clean and or replace spark plug. Best of luck.

Earthquake tiller viper 43cc engine will not start

I have the same issue, I thought it was the carburetor so I cleaned it and put it back together, same issue, I put a new carburetor on it same issue, has great spark, if I spray carb cleaner into it, it will start and run for a few seconds even throttle up, but then it dies, and will not start again without carb cleaner spray, and fuel is fresh and properly mixed, very confusing indeed.
