Poulan GHT-22 Hedge Trimmer The Primer Button Will Not Inflate

I Have a Poulan Weedeater GHT-22 Hedge Trimmer and the Primer Button Will Not Inflate and I am Trying to Pump the Fuel Line. The Fuel Lines Have Been Replaced. The Fuel Lines Leak Near The Handle When I Try To Prime It. Which Makes This A Very Difficult Task To Do. How Do I Repair This Problem?

It Also Has Trouble Cranking On Demand and Staying On,

Any Help Will Be Greatly Appreciated,

When changing the fuel lines did you get them back in the correct location? This would prevent the bulb from working. Also, if the bulb is old and brittle or leaking, would also cause hard start or leaks around the handle.

SOURCE: I've replaced the fuel lines and installed a carb

My best guess is that you replaced the internal parts of the carb, but you did not clean it and adjust it well enough. Take the carb back off and clean out all of the passages with aerosol carb cleaner. Remove each of the adjustment screws and blow cleaner through them as well. Reset them by turning them gently clockwise until they seat, then turn counterclockwise 1.5 turns each. This is a good starting point. Make sure the needle arm in the carb is set at the correct height. If you have a Zama carb, you can use a straight edge to set the height. Lay the edge across the carb (where the diaphragm will be) and check to see that the needle arm is just even with the edges of the carb.. If you have a Walbro carb, you will need to get the Walbro tool (WB 500-13-1) to get the needle arm set to its proper height. An arm that is set too low, will starve the engine and one that is too high will flood it. Also make sure the gaskets are installed in the proper order. Diaphragm side, the gasket goes on first, then the diaphragm. On the metering plate side, the metering pump goes on first (thinner one) then the gasket goes on, then the outer plate.
Don't forget to replace the inlet strainer (small screen).

On to fuel lines. You Weedeater product uses 2 sizes of fuel line. The smaller line must connect to the fuel filter in the tank, and then to the fuel port on the carb that is opposite the diaphragm. The fuel port that is closest to the diaphragm will connect the larger line. This is a return line and will go back to the tank. It may or may not have a small fitting on the end of it in the tank.

Now try a test run again. If it will idle, but not rev up, open up the Lo adjustment screw (closest to the engine) by turning it counterclockwise 1/4 turn. Test run. No change? go another 1/4 turn. If after all this, it is still not running properly, then there is a fault in the carb and it will need to be replaced.

Good luck!

There are 2 different set ups for fuel lines on these 2 stroke carburetors. One has a remote primer/purge bulb and the other has the primer/purge bulb on top of the carburetor. Here are instructions on how both kind work and how to service them.

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. If the purge/primer bulb is on top of the carb...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 If you have any more questions, please post back. I will see your comment and be glad to help you,

GHT 225 Trimmer Replaced primer bulb, Starts OK but, will not keep running.

Try adjusting the low side screw on the carb. Back it out about 1/8 of a turn at a time until engine continues to idle. If this this doesn,t solve your problem then you will have to disassemble the carb and replace the diaphragms and fuel filter screen.

I just put new fuel line on my trimmer now i cant start it not getting fuel the line never fills with fuel but i can **** fuel out so i know it not pinched it a weedeater brand ght-17

Make sure the little valve under the tank if you have one is fully turned clockwise. Make sure there is nothing clogging the tiny screen inside the fuel tank. Check or test your primer bulb it may be leaky. If carb or intake is leaking, you won't get gas either. If you have a filter on this model, try changing it.
