    I have a tiller with a separate fuel primer bulb. I have two lines from the bottom of tank. One of those lines is connected to the fuel filter. The other is a hose only (probably for intake side of bulb?) I have two outlets on carb. One on the diaphragm side and the other on the return side of the carb. Any help would be greatly appreciated.

Cultivator won't start.


After sitting for that long the carburetor will gum up and not let gas through. Buy a carburetor repair kit and replace the diaphram and gaskets. Be sure to make a sketch of where the fuel lines are routed to. It's easy to forget where they went and a headache to try to figure out. If it has a primer button I would replace that also.

Tiller wont get fuel to start


Try disconnecting the line at the carb. Then carefully blow back to the tank. It may have something blocking the outet from the tank. If that doesn't do the trick, the float may be stuck and not allowing the needle to open for fuel to enter the carb bowl. Good luck...Lee
