Sorry about the delay.
Problem solved, I hooked up the lines (very important to get a drill the size of your new gas line, it aids in sealing the tank, thus providing a good seal for the prime).
The thing in the bottom of the tank, attached to the line is a filter. It is available at any small engine shop).
Once I hooked up the lines and hit the primer ball a few times you can see the fuel moving, you will know, because you will see which way it flows through the lines. The other line is just a return line into the tank.
It is the same on generally any 2 cycle blower or weedwacker motor.

The diameter of the fuel lines are bigger then the holes in the fuel tank. Make sure u get the right diameter fuel line. The fuel lines are basically crimped by pressure. Sometimes its like there welded in place. There should be two fuel lines. One is short goes from carb to tank. When you use the primer bulb it takes fuel from tank through carb spits it back into tank. The longer one has the fuel filter on it. Empty all the gas from tank. Look inside of tank with a flashlight and try to locate the fuel filter. Take a piece of wire make hook on one end. Try to snag the fuel filter and pull out. Might as well replace filter while it is out. Take a pair of long nose pliers and grip the hose as close to the hole as possible. Try to pull with even pressure(no yanking). The lines may break because they could dry rotted. Make sure to hook lines back up the same way they came off carb.
You should have 2 to the tank, the one with filter coming from tank goes to nipple on right side of carb, the nipple on left side by primer bulb goes to primer bulb and other from primer bulb back to tank as return line, how it should work is when you push primer bulb it pulls fuel from tank through carb and back to tank on return line so watch in tank orleave one line out that you think is return line and see if gas comes out when you prime, but remember it goes through the carb first before it goes back to tank, had a pic but too big to put on site sorry, 2StrokeJim
Hi There, Check the primer bulb for tare or pin holes. Replace it. Check and clean carb jet it maybe plugged with debree. Also check for spark which you didn't say. Replace with correct plug.
Note; Do not use strong cleaners on rubber seals (O rings and gaskets) They dry up and crack.
If needed use a dabble of grease on seals
Fuel hose from the tank with the filter on the end goes to the fuel inlet on the carb ( nearest to the pump cover held eith a single screw ) then tak a pipe from the other cinection on the carb to the short conection on the back of the primer ( suction side ) then tak a pipe from the longer conection on the primer ( pressure side ) back to the tank, the primer pulls fuel from the carb and dumps it back to the tank.
If the lines dry rotted, some of it probably go into the carburetor. There is a very fine mesh screen inside the carb that traps this sort of trouble. Take the carb off and remove the cover on the end of the carb that doesn't have the hole in it. Find the screen underneath the fuel pump diaghram and clean it with non-flammable brake cleaner spray. This is a very common problem on all these machines....
your fuel lines are probably old & brittel they are the first thing to leak on those sometimes they leak around the tank but they are really thin lines & they get hot from engine heat & dry rot easly replace both lines from carb to tank & the leak will be gone most lines are 1/4 lines in most cases
It shouldn't have a electric fuel pump. What I would do first is take the gas tank off. Take the fuel line off. Drain the gas tank. blow thru the fuel line.put all back on and fill with gas and try again. I'm guessing it sat for awhile. when gas sits for awhile it gets tarnished.any little bit od debris that was in the gas tank could plug the fuel line. Hope that helps You out.
Well I finally got my saw running - it occured to me that my older chainsaw never had a primer bulb - so I bypassed it and...pull started it with the choke on till it chugged - then turned the choke off and held the gas full on - pulled the starter cord and was cutting trees - LOL
I did speak with a small engine guy - he explained that the primer is to pressurize the gas tank - so your return line from the carb goes to the suction side of the primer bulb - output to the tank - and pickup line with filter goes to the intake of the carb - FYI - hope it helps ya!!!!!!!!!!
